Question
Figure (i) shows the circuit diagram of a chopper. The switch in the circuit in figure (i) is switched such that the voltage across the diode has the wave shape as shown in figure (ii). The capacitance is large so that the voltage across it is constant. If switch and the diode are ideal, the peak to peak ripple (in A) in the inductor current is ______
Correct answer
2.49 to 2.51
Solution
From the waveform in Figure (ii):
- The switching period .
- The ON time (when ) is .
- The duty cycle .
- The supply voltage .
- The output voltage .
