The power electronic converter shown in the figure has a single-pole double-throw switch. The pole P of the switch is connected alternately to throw A and B. The converter shown in figure is _____?
A DC chopper is built employing an electronic switch as shown below. Determine the power absorbed by the switch. Assume switch to be ideal.
A Boost converter operates with D = 1, then output voltage will be __________?
The given figure shows a step-down dc chopper. A freewheeling diode is placed across the load. The load current varies between the limits of 10 A. The time ratio would be __________.
In step down converter, output voltage V0 is held constant at 5V by varying the duty cycle α. If dc input voltage varies from 10-40 V, output power P0 ≥ 5W and frequency of switching is 50 kHz then minimum value of ‘L’ required to keep the converter operation in a continuous condensation mode is_____?
A Buck converter is designed to produce an output voltage of 5 V from a 9 V dc source. It is connected across a load resistor of 75 Ω. Determine the value of inductance that will ensure continuous current for the switching frequency of 450 kHz.
In the circuit shown all elements are ideal and the switch S is operated at 10 kHz and 60% duty ratio. The capacitor is large enough so that the ripple across it is negligible and at steady state acquires a voltage as shown. The peak current in amperes drawn from the 50 V DC source is ________. (Give the answer up to one decimal place.)
