# A sinusoidal AC voltage source feeds a pure inductor through a diode as shown in the figure. The duration of conduction (in degrees) of the diode in one input power cycle is

### Right Answer is:

360°

#### SOLUTION

The waveform of the source voltage, inductor voltage, and inductor current for the above circuit is shown in figure

- From the waveform of inductor current i
_{0}we can observe that the current in the circuit is unidirectional (i.e. current through the diode only flows in one direction) and flows for the entire 2π duration. - As the current is unidirectional it means the diode doesn’t undergo reverse bias condition and hence is in the forward bias or on the state for the entire 2π duration.
- Therefore, the duration of conduction (in degrees) of the diode in one input power cycle is 360°.
