Title:
VOLTAGE CONTROL METHOD FOR CAPACITOR
Document Type and Number:
Japanese Patent JP3309259
Kind Code:
B2
Abstract:
PURPOSE: To make uniform the voltage being born by each capacitor in a short time while minimizing the leak current of voltage division resistors.
CONSTITUTION: When a specific charging power supply V1 is connected across a charging means comprising a series connection of a plurality of capacitors C1, C2, each capacitor C1, C2 is connected in parallel with a smoothing (voltage dividing) resistor R1, R2 through a switching means SW1, SW2. The switch means SW1, SW2 are turned ON when the charging voltage being fed from the charging power supply V1 is varying. When the charging voltage is not varying and the charging means is performing a voltage holding operation, the switch means SW1, SW2 are turned OFF to make uniform the voltage being born by each capacitor C1, C2.
