Title:
RECTIFYING POWER SUPPLY CIRCUIT
Document Type and Number:
Japanese Patent JP2009254125
Kind Code:
A
Abstract:
To provide a rectifying power supply circuit which makes switchover between single rectification and double rectification by changing component mounting, suppresses harmonic current through a reactor, and is miniaturized by miniaturizing a printed wiring board.
In the rectifying power supply circuit, the reactor 103 is connected at the rear of a diode bridge 101, and the reactor 103 and a first capacitor 107 share the position of mounting on the printed board 123. Hence the rectifying power supply circuit is miniaturized.
