Hi,
Iam designing a pwm inverter(phase). I need to produce a variable frequency supply ranging from(1~100 Hz). Is there any IC readily available to produce pwm pulses (two channel), whose reference sinusoidal frequency can be varied by giving a voltage to that IC.

ThanQ

Same OP, same question, same answers. You'd be better sticking with the original thread.

There is no simple single answer. There are chips that will allow you to build PWM and H bridges without shoot through, but nothing that does exactly what you want.

While you are researching H Bridges and PWM, also look up a class D amplifier, which is pretty close to what you want.

You never responded to my posts in your original thread as far as I know. Repeating the same question over and over won't change the responses, but it does fustrate the people you are asking for help from.

 

onlyvinod56,

You would be better off confining your posts on the same topic to the same thread that you launched earlier.
