Can you be more specific in your question please? You have a PWM drive circuit (what voltages, what frequencies?) that you want to connect to a motor's H-bridge transistor drive circuit? Can you please post schematics of what you are asking about?

i hv a problem about design a h-bridge multilevel inverter.
Question is wat components and model should use in multilevel inverter?
 
  • #5
if i use 7493(4 bit binary counter), it only can count up to 16(decimal), so how do use two 7493 connect together to let it count up more digits? use 1st 7493 ouputs connect all together go through into a "and gate" then connect to 2nd 7493?

second question, how do i preset it count up from " 1000" not start from "0000"?
thanks
