Question

draw and explain the circuit digram and waveform of a stepdown chopper.also derive the expression of the output voltage.​

Answer 1

Answer:

Step down chopper as Buck converted is used to reduce the i/p voltage level at the output side. Circuit diagram of a step down chopper is shown in the adjacent figure. When CH is turned ON, Vs directly appears across the load as shown in figure. So Vo = VS.
