Q.1. What is the function of bleeder resistor in a power supply? Answer: Bleeder resistor not consume too much power while supply is on and voltage decay quickly to safe level when the supply is switched off. So, the function of bleeder resistor is to ensure a minimum current drain in the circuit. Q.2. What are Mc Murray inverters? Answers: Mc Murray inverters are force-cumulated inverters. In ...
[1] What is full converter? What is dual converter? Full converter: When positive as well as negative half cycles of the supply are rectified, it is called full converter. Dual converter: When the polarities of output voltage as well as current can be reversed then it is said to be dual converter. It operates in all the four quadrants of the VO – IO plain.
