Figure 4. Six phase firing board
What Are The Applications Of Firing Boards?
What in the world are firing boards? Well, we will use this section to look at some of their top applications.
Before we look at that, it is important to note that firing boards primarily help you to control or regulate the phase angle of Silicon Controlled Rectifiers – SCRs in a dependable and cost-effective way. This is especially true in applications like converters that depend on DC and AC controllers.
You can use firing boards in devices and equipment like:
- DC motor drives
- Primary controllers for transformers
- Charging systems for batteries
- Wind turbine plant controllers
- Transformer primary controllers
- Half-wave converters
- Uninterrupted power supply systems.
What Does Firing Angle Mean In Firing Board?
Firing is a process where voltage is applied to the gate or switch of a silicon-controlled rectifier.
The silicon-controlled rectifier is a device made of an anode, cathode, and gate. When voltage is applied across the anode and cathode of the silicon-controlled rectifier, the gate or switch acts as a regulation pin.
There are two types of firing: zero voltage cross-over and phase angle control firing.
Zero Voltage Cross Over:
This type of firing is a technique used to turn on a silicon-controlled rectifier when the AC voltage load is zero. In other words, immediately the voltage crosses the zero mark or value, the silicon-controlled rectifier switches on.
What is Firing Angle?
As we’ve already looked at, the silicon-controlled resistor or thyristor of a firing board turns on upon zero voltage crossing. The angle at which this occurs is called the firing angle.
Once you turn on the silicon-controlled resistor on the firing board, it moves or functions in cycles. These cycles can be measured in degrees. The degree value measured when the SCR is turned on is referred to as the firing angle.
How Can You Control The Firing Angle In Firing Board?
Yes, you can achieve firing angle control. This can be done when you alter the period that you apply the voltage to the SCR’s gate.
One way you can achieve this is by employing a remote input control to adjust the period you apply voltage to the switch of the SCR. By doing this, you exercise control of when the firing board turns on.
Firing angle control is super important in applications like regulating the speed of a fan motor speed. It can also be useful when you want to adjust the intensity of a light’s source.

What Is Firing Circuit In Firing Board?
The firing circuits of a firing board can be configured in three forms: R firing circuit, RC firing circuit, UJT firing circuit.
The firing circuit has unique characteristics as follows:
The thyristor and firing circuit should be electrically separated. At certain periods, the circuit needs to produce thyristor activating pulses.
What Are The Quality Standards Of Firing Boards?
Recognized industry bodies have set standards that guide the design and manufacturing of firing boards. This ensures only reliable, safe, and efficient boards are produced.
Below are some quality standards firing board standards:
IEC65 is a standard for ensuring the safety of firing board household devices.
IEC 60947-4-2 is a standard that checks low voltage switch gears and regulators like AC regulated motors and starters
IEC 61000-4 is a standard for firing boards that measures and tests its procedures for electromagnetic consistency.
How Are Firing Boards Produced?
Producing firing boards involves many processes. But the most important steps in the manufacturing processes are:
Here, you create a blueprint of the firing board using design software. Before designing, you need to carefully consider all the requirements of the board. Also, determine the right materials for your board based on its application.
By inputting the vital specifications of your board onto the design software, the software can help you generate a precise, and feasible virtual structure of the board.
The design needs to be verified by expert engineers before you move on to the next stage of the production process.
Once the design is complete and it is verified, you need to fabricate or print the various components of the firing board.
At this stage, the various components of the firing board are assembled together in a precise manner using advanced equipment and technology. The assembling of board components should be done following ISO and industry quality standards.
In this stage, you test the board with a testing machine to verify if it meets its performance requirement.
What Factors Should You Consider When Buying Firing Boards?
You need to consider many factors when buying a firing board for your equipment. Below are some of the important factors to consider before buying a firing board.
Requirement of the firing board device
You need to first, determine exactly what you want to use the firing board for. What is the application of the board? Once you determine this, you need to determine the requirements of the board. This will help you choose the right board for your equipment.
The credibility of the manufacturer
The next thing you need to check or consider is the credibility of the manufacturer who would supply the firing board. Always, purchase from a manufacturer with massive experience, expert engineers, and designers.
The ideal firing board manufacturer should follow ISO production methods and use IPC class quality standards. Buying from a credible manufacturer means you will get a reliable and high-performing firing board.
The materials for the firing board
Finally, the board should be made of standard industry materials. Different firing board devices are built with different materials. These materials used are mostly determined by the requirement of your device.
What Factors Determine The Cost Of Firing Boards?
The cost of firing boards is influenced by several factors. Some of these factors include:
Various firing boards have different designs. The design of a board is primarily determined by its application. Firing boards with simple designs and structures mostly cost low. On the other hand, boards with complex designs and big structures can be higher.
Materials for making firing boards affect its final cost. Depending on the application of a firing board, specific materials would be used. In cases where high-quality materials are used for a board, the cost of the board may increase.
Another factor is the number of materials used for the boards. Applications that require more materials for their boards may have a surge in their price.
Finally, the type of manufacturer you choose mostly determines the cost of the firing board. Boards from big manufacturers are mostly high.
Big manufacturers have huge experience, great expertise, and top equipment. They also use high-class standards for their boards. This makes the boards from these manufacturers higher than relatively small and new manufacturers.
Can You Use LSI On Firing Boards?
Yes, you can use LSI – Large Scale Integration for making firing boards. Why? This is because LSI makes it possible to use several transistors on a microchip.
With this, you’re able to build high-performing equipment on a small platform.
Why Are LSI Used On Firing Boards?
Large-scale integration presents massive benefits to the firing boards. This unique technology allows you to pack thousands of transistors on a single chip.
With this, you reduce cost significantly since you only need a small platform or material to build your fireboard. In other words, LSI makes firing boards cost-effective.
Another huge benefit of LSI technology is its potency to skyrocket the performance of the fireboard due to increased transistors. Furthermore, it makes the board reliable while achieving maximum results.
What Is A Bi-Polar Firing Board?
This is a three-phase firing board having 6 SCR. Bipolar boards can be arranged to function as AC controllers. When used as an AC controller, bipolar boards can reverse series.
Bipolar Firing Board
- A bipolar circuit makes it possible to change from one pole to another.
- It has regulator boards for various current and voltages
- It has 3 double sets of output switches or gates.
- Control input for soft start and stop that can be arranged separately.
- Analog command control input for delay angle.
What Are The Applications Of the Bi-polar Firing Board?
Bipolar fire boards help you to regulate SCR’s phase angle for direct current converters and AC regulators.
Some common applications of bipolar boards include primary regulators for transformers, charging systems for batteries, half-wave converters, uninterrupted power supplies, and plating rectifiers.
Thyristor Firing Board
How Can You Prevent Firing Board Failures?
Firing boards can fail due to many reasons. But the most common causes of board failure are poor design, manufacturing defects, and environment.
When a firing board is not well designed to meet its performance requirement, it makes it very liable to fail.
The board should be well designed considering the requirements of the equipment it will be used for.
The design should be well laid out and verified by expert engineers before the production of the board begins. During the design stage, the right materials based on the board’s requirements should be chosen.
High-quality design software should be used for the design to ensure quality designs that guarantee the efficient functioning of the board. On top of this, your design should be feasible.
When proper manufacturing methods are not used, your board will end up failing. When there are poor joints on the board, the board will likely fail.
All the joints on board should be well aligned. You need to ensure structural integrity when designing and building the board.
To avoid degradation of board parts, high-quality parts that meet the device’s operation requirement should be used to avoid board failure. You need to strictly adhere to firing board quality standards when manufacturing.
What Are Auxiliary Firing Boards?
To increase the performance of a firing board, you can add or connect other boards to it. These additional boards are called auxiliary boards. For example, you can add five auxiliary boards to give you higher performance.
With auxiliary boards, you can control voltages as high as 900 V.
Auxiliary Firing Board
What Are Some Of The Unique Features Of The 3-Phase Firing Boards?
The three-phase firing board comes with some unique features. In most cases, these attached features don’t depend on the 3 phase firing board.
Below are some of the unique attached features of the 3 phase firing board:
- It can regulate or accommodate high voltages
- It has substantial distances that make it possible for creepage.
- It has circuits that permit poles transition
- Additional six output gates or switches.
Can You Combine Firing Boards With Other Printed Boards?
Yes, you can combine firing boards with other circuit boards. You can combine firing boards with auxiliary boards, regulator boards, and other specific boards.
With this configuration, you’re able to gain tremendous control for your device.
What Is a High Voltage Firing Board?
High voltage firing boards are boards you can use to regulate equipment with high voltages. These boards mostly have pulse transformers with huge output switches or gates.
Because of its improved creepage distance, there is better isolation to the AC Path’s voltage. This ultimately supplements the activation current of the gate.
Is it Possible To Use High Voltage Firing Board As A Primary Transformer Controller?
A transformer is a system that is used for transmitting electrical power. It is mostly used to increase or decrease a supplied voltage while maintaining the AC frequency between circuits.
In other words, a transformer can receive a voltage at a specific value and step up or step down the voltage values.
The following features of a high voltage firing board make it possible to be used as a primary controller for a transformer:
- You can make it work at once without hindering phase loss.
- It gives you more flexibility when it comes to regulating power points.
- High voltage firing boards are unresponsive to an increase in frequency values and warped main voltages.
Why Do You Use Silicon For SCR Firing Board?
