For a step-up/step-down chopper, if (duty cycle) = 0.5 then
A step down chopper has input dc voltage of 220 V and R = 10 in series with L = 65 mH. If the load current varies linearly between 11 A and 17 A, then find the duty cycle .
A step down chopper has Vs = 230 V and R = 10 . For a duty cycle of 0.4, the power taken by the chopper is 2097 Watts. Find the chopper efficiency. Take the voltage drop across the chopper switch as 2 V.
For a step-up/step-down chopper, if the duty cycle > 0.5 then
The expression for a step-up/step-down chopper with as the duty cycle and Vs as the dc input voltage is
