RECTIFICATION EFFICIENCY NOTE

(a full wave circuit has twice these efficiencies)
As the frequency of the input signal is increased, the
reverse recovery time of the diode (Figure 9) becomes
significant, resulting in an increase ac voltage component
across RL which is opposite in polarity to the forward
current, thereby reducing the value of the efficiency factor
, as shown on Figure 10.
It should be emphasized that Figure 10 shows waveform
efficiency only; it does not provide a measure of diode
losses. Data was obtained by measuring the ac component of
V
O
with a true rms ac voltmeter and the dc component with
a dc voltmeter. The data was used in Equation 1 to obtain
points for Figure 10.
