(A) 33.3 %
(B) 40.6 %
(C) 66.6 %
(D) 72.9 %
Solution:
The maximum efficiency of a half-wave rectifier is 40.6%. The proportion of dc output power to input power is used to define a rectifier’s efficiency.
Table of content
A half-wave rectifier’s efficiency will be:
η = Pdc/Pac
η = Vdc2/RL/ Vrms2/RL
VDC = DC or average output voltage
RL = Load Resistance
The output DC voltage or average voltage of a half-wave rectifier is determined by:
VDC = Vm/π
RMS voltage for half-wave rectifier is written as:
Vrms = Vm/2
Half-wave rectifier efficiency is:
η = (Vm/π)2/ (Vm/2)2 = 40/6%
Maximum efficiency for a Half wave rectifier = 40.6%
Summary:
The Maximum Efficiency of a Half-wave Rectifier is? (A) 33.3% (B) 40.6% (C) 66.6% (D) 72.9%
A half-wave rectifier can operate at a maximum efficiency of 40.6%. The rectifier efficiency is measured as the ratio of dc output power to input power.
