I have been trying to design this H-bridge circuit as a little project. I cannot seem to get the output I want and I am not sure why. At the output I am getting a constant voltage line instead of a PWM signal that shows switching at 42kHz.
So my questions are:
- What is wrong with my circuit for why I am unable to a PWM signal at the output?
- How can do we design the H-bridge to make sure it switches at our desired switching frequency?
Any help would be much appreciated.
I have changed the A-side gate drive signals into the MOSFETS
I have connected the DIS pin to ground
