Series Operation
Ripple
・
The following (1) and (2) of Series operation can
・ Ｔｈｅ
value of max ripple voltage is a value unde
be used. However, Use the output current below
the JEITA measuring method in the shielding
the max output current in small one either of power room.
(Refer to the below)
supplies with which the series is connected.
If neither the electrolytic capacitor nor the film
capacitor, etc. are connected with the load edge,
the ripple on the load edge might become large
when the load line becomes long.
Also, you can not measure correctly when the
ground lead of the oscilloscope is long .

Parallel Operation

Parallel operation can not be used for the purpose
to increase output current.
