電源装置および画像形成装置
Document Type and Number:
Japanese Patent JP7010140
Kind Code:
B2
Abstract:
To provide a power source apparatus in which the time required for invalidating a start switch can be shortened while an increase in the cost is suppressed.SOLUTION: The power source apparatus for supplying a power source to a unit, includes a converter that outputs a first DC voltage by performing conversion of an AC voltage, a power storage device that outputs a second DC voltage, a feedback control unit that stabilizes the first DC voltage by performing feedback control on a switching operation of the converter on the basis of a third DC voltage obtained by dividing the first DC voltage, discharging means that discharges an electric charge stored in a block capacitor when supply of an AC voltage to the converter is interrupted, switching means that operates with a discharge current obtained by the discharging and stops the switching operation by switching a circuit configuration for voltage division and by changing the third DC voltage, and invalidation means that invalidates a start switch provided to the unit, in accordance with the stop of the switching operation.SELECTED DRAWING: Figure 1
