-5-3-3 DC OUTPUT
DC output is taken out from the DC coil and is fed to the diode stack (rectifier) where the output undergoes
thedirection @, but doesnotallowthecurrent to flow in the direction8, as shown in Fig.
Fig. 5-8-2 shows the DC output circuit of the gener- ator. DC voltage is generated in the DC coil. When the voltage in A is higher than that in Cythe current
@flows in the direction shown in the figure, while
nocurrentflows between B and C becausethe current is cut off by the diodesD,.
On the contrary, when the voltage in C is higher than that in A, the current @ flows in thedirection as shown in the figure.No current flows betweenA and B because the current is cutoff by the diodes D,.

As a result, the voltage generated at the output terminalhas a wave form with two peaks in one cycle, as in the caseof the output wave form shownin Fig.

CAUTION :Do not use DCand AC output simultaneously.
- Due to a characteristic of the condenservoltageregulation,simultaneous use ofDC and AC output creates voltage drop In DC output resultingin incapability for charging batterles.
