Title:
RECTIFIER CIRCUIT
Document Type and Number:
Japanese Patent JP2011135758
Kind Code:
A
Abstract:
To provide a rectifier circuit that can be operated safely without causing any damage on a device, even though an inrush current flows at recovery from a power interruption or at turning-on the power.
A high power factor rectifier circuit, provided with switchs connected to an AC power supply for converting an AC voltage to a DC voltage, is formed with a bypass circuit provided. The bypass circuit, when the voltage of the AC power supply becomes higher than the voltage across a smoothing capacitor provided on the DC output side, makes a charge current flowing from the AC power supply to the capacitor bypass the switch by making the switch out of conduction.
