Q: What is the form factor of Full wave rectifier?Īns: The form factor of the full wave rectifier is 1.1. Smoothing circuits have smaller ripple value and they also reduce the AC part of the output signal. Q: How do you increase the efficiency of a rectifier?Īns: The best way to increase the efficiency of rectifier is to use smoothing circuits. Maximum efficiency is obtained when Sin θ is 1 and Minimum efficiency is when Sin θ is 0. Q: What is the Maximum and minimum efficiency of a Full wave rectifier?Īns: The maximum efficiency of a full wave rectifier is 81.2%. Q: What is the formula of Full wave rectifier efficiency?Īns: The formula of efficiency of full wave rectifier is η = DC Power Output / AC power input.

The diagram given below shows the input voltage wave and rectified output wave. We take r f as the forward resistance of crystal diode and R L be the load resistance of the circuit. And as we have to find maximum efficiency, we will take it as variable and suppose it to be V m sin θ. Let the AC voltage applied (input voltage to be rectified) is v. Full Wave Rectifier Efficiency Calculation: The efficiency of a full wave rectifier is defined as the ratio of DC power output to the applied input AC power. I am going to describe all of these one by one in this article.
