(3) Smoothing capacitor C501,C52,C503
This smoothes (averages) the voltage rectified by the diode stacks.
● Be careful to avoid an electric shock as a
high voltage is generated. Also take care
not to cause a short-circuit through incorrect
connection of test equipment terminals. The
circuit board could be damaged.
(4) Smoothing capacitor (C020, C021)
This smoothes (averages) the voltage rectified by the diode stacks.
A DC voltage is generated in the same way as in Fig. 1-3. Voltage between 丣 side of C020 and 両 side
of C021 is about 330V.
