Q#1 Chopper GATE EE 1995 MCQ +1 mark -0.33 marks

A dc to dc transistor chopper supplied from a fixed voltage dc source feeds a fixed resistive-inductive load and a free-wheeling diode. The chopper operates at 1 kHz and 50% duty cycle. Without changing the value of the average dc current through the load, if it is desired to reduce the ripple content of load current, the control action needed will be:

Increase the chopper frequency keeping its duty cycle constant

Increase the chopper frequency and duty cycle in equal ratio

Decrease only the chopper frequency

Decrease only the duty cycle.
