ncerthelp.com(ii) Frequency Modulation In this type of modulation, the frequency of high frequency carrier wave is varied in accordance to instantaneous frequency of modulating signal. (iii) Pulse Modulation In this type of modulation, the continuous waveforms are sampled at regular intervals. Information is transmitted only at the sampling times. Demodulation
Pulse Width Modulated (PWM) Drives - Rockwell Automation
literature.rockwellautomation.comPulse Width Modulated (PWM) drives. In this type of drive, a diode bridge rectifier provides the intermediate DC circuit voltage. In the intermediate DC circuit, the DC voltage is filtered in a LC low-pass filter. Output frequency and voltage is controlled electronically by controlling the width of the pulses of voltage to the motor.
