Title:
POWER UNIT WITH STANDBY POWER REDUCTION CIRCUIT
Document Type and Number:
Japanese Patent JP3881990
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a power unit with a standby power reduction circuit which can reduce troubles of the power unit with a snubber circuit in an electronic apparatus equipped with a standby mode and can achieve energy saving at the same time.
SOLUTION: The snubber circuit in the power unit equipped with the power unit with a standby power reduction circuit is constituted of at least capacitors and two parallel resistors as a parallel circuit, and equipped with a switch which is turned off by a standby mode input signal connected in series with one of the resistors. The snubber circuit in an operation mode has two resistors connected in parallel to each other. When the standby mode switch is turned on, one of the parallel resistors automatically turns off the switch connected in series to the resistor by the standby mode input signal to save the power.
