I have a PWM signal at 100Hz ("Vg" label at circuit) with variable duty cycle (10%-90%). Because I had voltage spikes I managed to eliminate them by placed three capacitors which types and values are below. My query is if the ESR of these capacitors is right for this frequency (100Hz) that I am using and if no which value of ESR is the right?
P.S. I don't want to place ceramic capacitors because they produces an acoustic noise/buzz.
