Hi,
I am working on multilevel inverters using cascaded H-bridge topology. But I am confused on how to apply a PWM signal to H bridge for this application. As it is multilevel inverter so the signal voltage should increase step by step so PWM should be used. But I am confused that do I need to apply PWM to all MOSFETS or only one PWM needed as used in L293D(motor speed control application) but for L293 got Enable signal but how to do that in H-bridge made of mosfet?
