Abstract:
A power conversion circuit comprises a heating member, a series connection that connects a capacitor and an induction coil, and a control circuit. The heating member heats a toner image formed on a print medium. The series connection connecting a capacitor and an induction coil that generates a magnetic field to the heating member is connected between a first connection point and a second connection point. The control circuit switches, based on the voltage detected by the voltage detection section, between a first operation mode and a second operation mode, wherein in first operation mode, pulse signals are input to the first to fourth switching elements, and in second operation mode, pulse signals are input to first switching element and the second switching element, third switching element is turned off, and fourth switching element is turned on.

Claim (Index 1):
An image forming apparatus, comprising:\n a heating member that heats a toner image formed on a print medium to fix the toner image onto the print medium, a rectifying circuit configured to rectify an AC power supply; a first switching element connected to a positive terminal of output terminals of the rectifying circuit; a second switching element connected between the first switching element and a negative terminal of the output terminals of the rectifying circuit; a third switching element connected to the positive terminal of the output terminals of the rectifying circuit; a fourth switching element connected between the third switching element and the negative terminal of the output terminals of the rectifying circuit; a series connection of a capacitor and an induction coil configured to generate a magnetic field at the heating member, the series connection being connected between a first connection point connecting the first switching element and the second switching element and a second connection point connecting the third switching element and the fourth switching element; a voltage detection section configured to detect a voltage of the AC power supply; and a control circuit configured to switch a mode between a first operation mode in which pulse signals are input to the first to the fourth switching elements and a second operation mode in which the pulse signals are input to the first switching element and the second switching element, the third switching element is turned off and the fourth switching element is turned on.
