Abstract
A power conversion circuit has an inverter circuit including a first node and a second node that output a voltage according to an input voltage, a resonant circuit connected to the first node and the second node and including a third node and a fourth node that output a resonant voltage; and an output circuit connected to the third node and the fourth node and configured to output a DC voltage, wherein the resonant circuit includes a first inductor having one end connected to the third node, a first capacitor connected between the first node and another end of the first inductor, a second capacitor connectable between the second node and the fourth node, a second inductor connectable between the third node and the fourth node, and a first switch that switches whether or not to connect the second inductor between the third node and the fourth node.
