Share buttons are a little bit lower. Published by Myrtle Dickerson Modified about 1 year ago. A variable dc voltage is obtained from a constant dc voltage source. Also known as dc-to-dc converter. Widely used for motor control.

Also used in regenerative braking. Thyristor converter offers greater efficiency, faster response, lower maintenance, smaller size and smooth control. In step down chopper output voltage is less than input voltage. In step up chopper output voltage is more than input voltage.

The thyristor in the circuit acts as a switch. When thyristor is ON, supply voltage appears across the load When thyristor is OFF, the voltage across the load will be powwr. Pulse width modulation control or constant frequency operation. To obtain full output voltage range, frequency has to be varied over a wide range.

Current flows from supply to load. Step-up chopper is used to obtain a load voltage higher than the input voltage V.

The values of L and C are chosen depending upon the requirement of output voltage and current. When the chopper is ON, the inductor L is connected across the supply.

The current tends to decrease resulting noets reversing the polarity of induced EMF in L. Diode D prevents any current poweg from capacitor to the source. Step up choppers are used for regenerative braking of dc motors.

Duty cycle d can be varied only between a min.

Ripple in the load current depends inversely on the chopping frequency, f. To reduce the load ripple current, frequency should be as high as noyes.

If the load voltage is volts, calculate the conduction period of the thyristor in each cycle. The output required is V. Compute Chopping frequency, If the pulse width is halved for constant frequency of operation, find the new output voltage.

UNIT III DC Choppers.

When chopper is ON, its voltage drop is 1. When chopper is ON, its voltage drop is 2 V and the chopping frequency is 1 kHz. M Buck Converter Objective is to answer the following questions: How does a buck converter operate?
