Question

Quizplus · Accepted Answer

A chopper circuit is also known as a DC-DC converter because it is used to convert one DC voltage level into another DC voltage level by varying the duty cycle of a high-frequency square wave. The output of a chopper circuit is pulsating DC, which can be filtered to produce steady DC. Therefore, the correct choice is D, which is to change steady DC into pulsating DC.
