摘要：PURPOSE: To charge each capacitor with a large electrostatic capacity or

efficiently even if an initial charging state scatters. CONSTITUTION: The title system is

provided with an initialization mode for performing initialization by discharging the

residual electric charge of capacitors C1 and C2 which are serially connected and a normal

charging mode for charging each capacitor by a specific amount and initializes each

capacitor and then execute the normal charging mode in the initialization mode.

Rectification elements D1 and D2 in opposite direction to normal charging are connected

in parallel with each capacitor and at the same time a connection polarity switching means

2 of the POWER supply for charging is connected and the POWER supply for charging is

connected in reverse polarity by a switching means or switching elements M1 and M2 are

connected in parallel with each capacitor and thus discharging the residual electric charge

of the capacitor by bypassing. Also, a control means 1 is used to judge whether

initialization requirements are met or not and thus selecting whether the initialization

mode is executed or only the normal charging mode is executed.
