PWM driven power supply [closed]
As you have asked me, I will explain in better words my problem. I’m working on real-time bench. I have an algorithm on my laptop and I interact with hardware through a calculator supporting real-time...
View Articleswitching power loss calculation in sinusoidal pulse width modulation
How do i calculate the switching power loss in sinusoidal pulse width modulation SPWM in a H bridge inverter (4 IGBTs), and precisely is it linearly proportional to the frequency switching or to the...
