Full form of PWM.

(a) Pulse width modulation

(b) Pulse run modulation

(c) Power width modulation

(d) Pulse wisdom mode

This question was posed to me by my college director while I was bunking the class.

This is a very interesting question from Power Rating Determination of Electric Motors for Different Applications topic in section Rating and Heating of Motors of Electric Drives

Answer 1

The correct option is (a) Pulse width modulation

The best I can explain: PWM stands for pulse width modulation. This technique is used to alter the voltage level of the output of the inverter. We can control the voltage level using the PWM technique.
