The device used for converting continuous DC to discontinuous DC is known as a/an
In the above figure, the load voltage is positive whereas the load current is negative. Thus, the current flows out of the load and into the source. Identify the type of chopper shown in the figure.
Which type of chopper is generally used in high power circuits where load fluctuation is not very large?
In line-side commutated circuit shown which component is to be replaced by an energy recovery transformer and a diode in order to limit overcharging of the capacitor?
In the figure shown, the chopper feeds a resistive load from a battery source. MOSFET Q is switched at 250 KHz, with a duty ratio of 0.4. All elements of the circuit are assumed to be ideal. Average source current in Amps in steady state is
