Title:
DISCHARGING CIRCUIT
Document Type and Number:
Japanese Patent JP2008187803
Kind Code:
A
Abstract:
To provide a discharging circuit with which a capacitor is discharged by using a thyristor and the thyristor is not continuously kept in an on-state.
An anode 6A and a cathode 6C of the thyristor 6 are connected through a transistor 7. The transistor 7 is turned on, self-holding of the thyristor 6 is released and the thyristor 6 is restored to an off-state if an operation of a commercial power supply 1 is resumed when the thyristor 6 is in the on-state by self-holding.
