ORDERING INFORMATION
See detailed ordering and shipping information in the package
dimensions section on page 6 of this data sheet.
For a square wave input of amplitude Vm, the efficiency factor
becomes:
(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 10) becomes significant,
resulting in an increasing AC voltage component across RL which is
opposite in polarity to the forward current, thereby reducing the
value of the efficiency factor σ, as shown on Figure 9.
It should be emphasized that Figure 9 shows waveform efficiency
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.
