Title:
電源装置及び画像形成装置
Document Type and Number:
Japanese Patent JP6824708
Kind Code:
B2
Abstract:
The power supply apparatus includes a detecting unit that has a first detecting device, a second detecting device and a third detecting device, detects a current flowing into the primary winding, and outputs a voltage corresponding to the current, and a control unit that controls a switching operation of the switching element, an output voltage which the detecting unit outputs to the control unit includes a first output voltage at which the control unit stops an operation of the switching element at a time of the second state, a second output voltage at which the control unit stops the operation of the switching element at a time of the first state, a third output voltage at which the second detecting device is brought into a conducting state, and a fourth output voltage at which the third detecting device is brought into a conducting state.
