library.e.abb.comBoth voltage and frequency reference are fed into a modulator which simulates an AC sine wave and feeds this to the motor’s stator windings. This technique is called pulse width modulation (PWM) and utilises the fact that there is a diode rectifier towards the mains and the intermediate DC voltage is kept constant.

www.nxp.comFor each channel, the audio input signal is co nverted into a digital Pulse Width Modulation (PWM) signal using an analog input stage and a PWM modulator; see Figure 1. To drive the output power transistors, the digital PWM signal is fed to a control and handshake block and to high- and low-side driver circuits .
