(A full wave circuit has twice these efficiencies)
As the frequency of the input signal is increased, the re-
verse recovery time of the diode (Figure 10) becomes signifi-
cant, resulting in an increasing ac voltage component across
RL which is opposite in polarity to the forward current, there-
by reducing the value of the efficiency factor
σ
, as shown on
Figure 9.
It should be emphasized that Figure 9 shows waveform ef-
ficiency only; it does not provide a measure of diode losses.
Data was obtained by measuring the ac component of Vo
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 9.
