FAQs on Half Wave Controlled Rectifier (RE & RLE load) Part - 3, Power Electronics, Electrical Engineering, GATE Video Lecture

1. What is a half-wave controlled rectifier?

Ans. A half-wave controlled rectifier is a circuit that converts an alternating current (AC) input into a pulsating direct current (DC) output by using a thyristor or other controlled electronic switches to control the flow of current in only one half of the input waveform.

2. What is the difference between RE and RLE load in a half-wave controlled rectifier?

Ans. In a half-wave controlled rectifier, RE load refers to a resistive load connected to the rectifier, while RLE load refers to a load consisting of a resistor and an inductor connected in series.

3. How does a half-wave controlled rectifier work with an RE load?

Ans. In a half-wave controlled rectifier with an RE load, the thyristor is triggered to conduct current for only a portion of the input waveform. During this conduction period, the current flows through the load and charges the load capacitor. When the thyristor is not conducting, the current is blocked and the load capacitor discharges through the load resistor, providing a pulsating DC output.

4. What is the advantage of using an RLE load in a half-wave controlled rectifier?

Ans. The use of an RLE load in a half-wave controlled rectifier helps to smooth out the pulsating DC output by introducing an inductor in series with the load resistor. This reduces the ripple in the output voltage and provides a more stable and continuous DC output.

5. What are the main applications of a half-wave controlled rectifier?

Ans. Half-wave controlled rectifiers find applications in various domains such as battery charging, speed control of DC motors, power supplies for small electronic devices, and voltage regulation in low-power applications. They are particularly useful when a simple and cost-effective rectification circuit is required.
