I am trying to drive H bridge using the following configuration I am producing an inverting.
4 * N channel mosfets Fdd8447 gate driver ic TC4428 (used alternatively IX4428 and IXDF604 but no avail) Frequency stays <15Hz Power rating remains within half a watt At the Output I have 2.2K Ohm resistor 1Uf capacitor
I am not using IR2110 since I cannot produce the required +10V on high side gate as my max output amplitude stays within 20V. I am able to produce the required wave but I get wave this after applying the capacitor... otherwise worst...after adding the capacitor there is unusual sound in the gate driver as well...in fact I have even burnt one. Whats the problem?
Furthermore my load is not motor but a small and a capacitive one like the human skin
