How To Determine Parasitic Inductance In DC-DC Converter PCB?

Parasitic inductance is an unwanted inductance of DC-DC converter PCB. It is produced from the capacitors. Parasitic inductance is also known as series inductance. It creates significant problems in ensuring a stable DC voltage supply at the output.

So, you need to determine the parasitic inductance of it.

First, you have to calculate the impedance of the PCB to the frequency at maximum power load. You can draw an output impedance vs frequency graph.

Impedance VS Frequency Graph

Now, calculate the inductive reactance at any point on the graph. You can use the following formula:

Inductive reactance, = 2f L

Here, f= frequency (Hz), L= inductance (Henry)

Since impedance is a complex number, you need to consider the output inductance as a reactive value. Here, the regulating circuit can’t minimize the load current changes at 100 Hz frequency. Then, it acts like a voltage regulator having a little parasitic inductance.

What Is The Effect Of Parasitic Resistance In DC-DC Converter PCB?

Parasitic resistance hampers the effectiveness of a DC-DC converter PCB. Here, some adverse effects of parasitic resistance are explained for your convenience.

• It lacks stability due to parasitic resistance.
• Parasitic components draw extra electricity from the power supply along with creating noise and ripples.
• It decreases the output impedance. But, this PCB requires high impedance to operate.
• Parasitic resistance causes bouncing of the grounds of the PCB.
• It promotes resonance in the power distribution network (PDN).

That’s why you should try to reduce the parasitic resistance, inductance, and capacitance of PCB.

How To Minimize The Noise Of DC-DC Converter PCB?

DC-DC converter PCB suffers from noise during high-speed signal processing. Noise is an amalgamation of periodic ripple and spikes from external sources.  So, you need to minimize the noise to get maximum performance from it.

Here, some reliable ways of reducing noise are explained.

Boot Resistor

Using a boot resistor is an easy method to reduce signal noise. You have to place it with the bootstrap capacitor. It supplies the required charge to the driver of MOSFET. The boot resistor resists the current that is used in charging the driver.

It delays the turn-on of the MOSFET that leads to low noise. The boot resistor also lessens the EMI effect. You need to use the boot resistor carefully. Extra resistance can affect the functionality of the PCB.

Bypassing

Bypassing the PCB chips lessens the parasitic elements. So ESL and ESR are also reduced. That results in low noise in the power supply.

Snubber Circuit

There are capacitors and resistors in the snubber circuit. This circuit absorbs the stored energy of parasitic components. That’s why the switching node ringing is reduced.

Since switch node ringing promotes the noise, the snubber circuit reduces the noise. It also minimizes the output ripple and EMI of this PCB.

Ferrite Beads

Ferrite beads soak the noise and EMI through their resistance at high-frequency. You need to use the effective ferrite bead in this case. You can apply multiple ferrite beads for multiple loads.

Filtering Through Capacitors

You can minimize the noise through filtering. Capacitors are highly applicable in filtering. You just need to choose a capacitor having low ESR (Equivalent Series Resistance) and ESL (Equivalent Series Inductance).

Low Noise DC-DC Converter PCB

Feedthrough capacitors are a good choice in this case. It contains an additional terminal that minimizes the equivalent series inductance. So, it can filter high-frequency signals efficiently. You can use a feedthrough capacitor having the maximum insertion loss.

You can also apply an L-C low pass filter to reduce the noise and EMI of DC-DC converter PCB. watch this video: https://youtu.be/DPN1BERe6cg

Here, A= cross-sectional area (square mil)

b=0.725, c= 0.44,

correlation factor, K= 0.024 (internal layer); 0.048 (external layer)

= rise of temperature (⁰C)

DC-DC Converter PCB With Maximum Current-Carrying Capacity

How Can You Calculate The Efficiency Of DC-DC Converter PCB?

The efficiency of a DC-DC converter PCB is defined by the ratio of output power and the input power.

An ideal DC-DC converter PCB offers 100% efficiency. That means output power and input power are the same. But the scenario is different in the real case. Here, the output power is less than the input power.

You can calculate both powers by using this formula:

You have to take care of static and dynamic losses to increase efficiency.

What Are The Input-to-output Voltage Considerations In DC-DC Converter PCB?

DC-DC converter PCB changes the DC output voltage from the DC input voltage to ensure the voltage regulation in each component. So, you need to consider some matters related to input and output voltage.

• If you need a higher DC output voltage, use the boost converter PCB.
• Use buck DC-DC converter PCB if you require lower output voltage than input.
• In case you have to use both low and high output voltage compared to the input voltage, apply the buck-boost DC-DC converter PCB.
• Sometimes input and output DC voltages have different polarities. Then you can use an inverting DC-DC converter PCB.
