Question

A chopper circuit is operating on TRC at a frequency of (5 kHz) on a (3300) supply of the load voltage of (2500).

(a) Determine the conduction period of the thyristor in each cycle.
(b) What is the chopper efficiency assuming switch. Assume that it's ideal.

Answer 1

The conduction period of the thyristor in each cycle can be calculated using the formula: pi / f, where pi is the angle of conduction and f is the frequency. The chopper efficiency is 100% since the switch is assumed to be ideal and there is no power dissipated.

Step-by-step explanation:

(a) The conduction period of the thyristor in each cycle can be determined by using the formula: π / f, where π is the angle of conduction and f is the frequency. In this case, the frequency is 5 kHz, so the conduction period is π / 5000.

(b) The chopper efficiency can be calculated using the formula: (Vout / Vin) x 100%, where Vout is the load voltage (2500) and Vin is the supply voltage (3300). Since the switch is assumed to be ideal, there is no power dissipated, so the efficiency is 100%.
