How to Connect PWM to a Multilevel Inverter Using H-Bridge and MOSFET?

urgent...PWM--->Multilevel inverter

I hv a problem about the connection. i got this two circuits, but the problem now is how to connect this two circuits? Becoz, PWM only generates square waveform, and now , which circuit can i use to connect from PWM to Multilevel inverter(H-bridge method (mosfet))? thanks for helping me!

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?

Please be more specific. An H-bridge is generally used to drive a motor or other power component.

A power inverter is generally used to convert DC into an AC mains type of waveform:

After reading those two references, if you have specific questions, please post them here in this thread.

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
