A power conversion device (30) is equipped with a monolithic booster circuit that can perform a synchronous rectification. When the power conversion device (30) starts to shift from an asynchronous rectification state during which first switching is performed in which a second semiconductor switching element (307) is maintained in an off-state and a first semiconductor switching element (304) is switched between a first on-state and a first off-state to a synchronous rectification state during which second switching is performed in which the second semiconductor switching element (307) is switched between a second on-state and a second off-state in synchronization with the first switching, a control device (321) is characterized by performing control so that when the first semiconductor switching element (304) is in the first off-state in the synchronous rectification state, the second semiconductor switching element (307) is brought into the second on-state during a second on-time shorter than a first off-time indicating the time frame of the first off-state. |
