Hey there for the first time community.
So I'm on my first year studying electronics, and for our final project this year we were asked to design and build a variable PWM motor controller.
Everything was going fine until I reached the last bit of the design; using drivers to drive the MOSFETs. I honestly have no idea how to use them properly, but after many hours of searching the internet for tutorials I came up with a design that I thought would work. Unfortunately it doesn't, and I don't know where to go from here, so I'm asking you guys for help.
I'm attaching the file here, if anyone wants to have a look. The signal generator simulates the pulses that would reach the driver from the rest of the circuit. Instead of making the whole circuit in one big file, I'm dividing it into smaller parts to improve simulation speed.
What am I doing wrong? Why are the HO and LO pins not sending any pulses to the gate? What can I do to improve my circuit?
Any help appreciated.
