发明名称 Power supply control apparatus and image formation apparatus
摘要 In the image formation apparatus, an active filter converts an AC power supply supplied from an AC power supply to a DC voltage, and first and second DC-DC converters convert the DC voltage converted by the active filter to voltages at predetermined levels and respectively supplies the voltages to an image forming engine and an engine control unit. A power supply control unit stops the operation of the first DC-DC converter in order to allow the second DC-DC converter to continue supply of the voltage to the engine control unit when disconnection of the AC power supply is detected.
