What are the two modes of PWM generator?

What are the two modes of PWM generator?

Two methods are used to generate PWM signals digital method and analog method.

Why is PWM generator?

Description. The PWM Generator block implements a PWM generator. The pulse width modulation technique controls power transfer from one electrical component to another by quickly switching between full power transfer and no power transfer.

Which technique is used to generate PWM?

Pulse width modulation (PWM) is a modulation technique that generates variable-width pulses to represent the amplitude of an analog input signal. The output switching transistor is on more of the time for a high-amplitude signal and off more of the time for a low-amplitude signal.

How PWM pulses are generated?

Generation of Pulse Width Modulation (PWM) Signal Modulating signal forms one of the input to the Comparator and the other input is fed with a non-sinusoidal wave or sawtooth wave. It operates at carrier frequency. The Comparator compares the two signals and generates a PWM signal as its output waveform.
