Abstract

In accordance with an embodiment, a power circuit for supplying electric power to an image forming apparatus equipped with a drive system and a control system comprises a first power supply circuit configured to supply the electric power to the control system; a second power supply circuit configured to supply the electric power to the drive system; a first capacitor configured to smooth the electric power from a commercial power supply and to supply the smoothed electric power to the first power supply circuit; and a second capacitor having a larger capacity than the first capacitor and configured to smooth the electric power from the commercial power supply and to supply the smoothed electric power to the second power supply circuit.

Description

technical field [0001] Embodiments of the present invention relate to a power supply circuit and an image forming apparatus. Background technique [0002] The image forming apparatus performs printing according to a print request. The image forming apparatus has a driving unit such as a transport unit that transports paper, an image forming unit that forms an image on the paper, and a control unit that controls the operation of the driving unit. The image forming apparatus has operation modes such as a normal mode in which the driving unit is maintained in a state where the driving unit can be operated, and a standby mode in which the driving unit is stopped and the operation of the control unit is maintained. [0003] A power supply unit for an image forming apparatus performs full-wave rectification of a commercial power input through a diode bridge. In the power supply unit, a power factor correction (Power Factor Correction) circuit operates so that the phases of the i...
