Abstract:
The switching power supply apparatus including a transformer includes a detection unit configured to detect that the power supply apparatus malfunctions and a first holding unit configured to turn off a first switching element and holds the first switching element at turn-off condition, and when the detection unit detects that malfunction occurs, the first holding unit releases the first switching element from the turn-off condition at a timing when the control unit turns on the second switching element by a second control signal.

Claim (Index 16):
An image forming apparatus comprising:\n an image forming unit configured to form an image on a recording material; and a power supply apparatus to supply power to the image forming apparatus, the power supply apparatus including a transformer including a primary winding and a secondary winding; a first switching element connected in series to the primary winding of the transformer; a second switching element connected in parallel to the primary winding of the transformer; a capacitor connected in series to the second switching element and connected in parallel along with the second switching element to the primary winding of the transformer; a feedback unit configured to output information according to voltage induced in the secondary winding of the transformer; a control unit configured to control turn-on or turn-off of the first switching element by a first control signal and control turn-on or turn-off of the second switching element by a second control signal based on the information output from the feedback unit, the control unit configured to perform a switching operation of alternate turn-on and turn-off of the first switching element and the second switching element before and after a dead time in which the first switching element and the second switching element are both turned off, and a first holding unit configured to turn off the first switching element and holds the first switching element at a turn-off condition, wherein in a case where the detection unit detects that malfunction occurs, the first holding unit releases the first switching element from the turn-off condition at a timing when the control unit turns on the second switching element by the second control signal.
