engineering recuitment GATE EE 2023-24 Test Series Power Electronics and Drives Choppers Step Down Choppers
A step-down chopper has input voltage 200 V and o/p voltage 140 V. If the conduction time of thyristor chopper is 70 μ sec. Now if the frequency operation is increased by 25% keeping conduction time of thyristor constant than find the average value of new output voltage.
Enter numerical value using the virtual keypad. Round off where necessary.
