8-2-3 DC OUTPUT
DC output is taken out from the main coil and is fed to the
diode at which time the output undergoes full-wave recti-
fication prior to being supplied to the load connected to
the generator. The diode rectifier works to allow the cur-
rent to tlow in @ direction but does not allow the current
to flow in s direction as shown in Fig. S-3.
Fig. 84 shows the DC output circuit of the generator.
DC voltage is generated in the main coil; when the voltage
in
A
is higher than that in C. current !~flows in the direc-
tion shown in the figure while no current flows between C
and
B
because current is cut off by the diode
D2.
Contraq
to the aforementioned, if the voltage in C is higher than that
in
A,
current a flows in the direction as sholvn in the
figure. with no current flowing between A and B. This is
because the diode
Dl
cuts off the current between A and
B.
As a result. voltage generated between the DC terminals has
a waveform with t\vo peaks in one cycle. as in the case of
the output waveform shown in Fig. 8-5.
