Usually to vary output voltage In external type of control, circuit becomes bulky, we have to vary supply voltage which is not always costly and complicated so we go for internal control possible for this reason PWM techniques gained of inverter. In internal control inverter output voltage momentum. Basic aim of PWM technique is to can be adjusted by exercising the control within the control output voltage and harmonic reduction. inverter itself.
