Webinar: Why PID is not suitable to stabilize most power supplies

In this video Dr. Ali Shirsavar from Biricha Digital explains why PID compensators are not always a good choice in power converters and voltage regulators.

Great work Dr. Ali. I really hope you continue to push out educational content. Your content is very valuable to the engineering and technology community.

I wish you had done this for a linear power supply, where PID would be MAGIC!!!!!

well, you assert that power supplies must be designed in frequency domain, but you fail to justify that. I have designed switchers, and yes, I used frequency domain and typically a single integrator that never dropped phase margin below 90 degrees - perfect behaviour and a clean, overshoot-free switch-on. But just because that is a really good way to do it doesn't necessary preclude a TD method.

At 2:40, Dr. Ali Shirsavar mentions the advantage of PID is that one does not need to design in frequency domain. However, depending on the topology of the power supply a simple integrator might not be sufficient.

Hi Ali, Excellent explanation of why PID is not suitable.

Thank you!
