Abstract

A power converter including: a transformer; a primary-side full-bridge circuit including a primary-side coil of the transformer and a magnetically-coupled reactor, in which two reactors connected to both ends of the primary-side coil are magnetically coupled; a first port connected to a positive electrode bus bar of the primary-side full-bridge circuit; a second port connected to a tap of the primary-side coil; a secondary-side full-bridge circuit including a secondary-side coil of the transformer; a third port connected to a positive electrode bus bar of the secondary-side full-bridge circuit; a first search coil wound around a core of the magnetically-coupled reactor; a second search coil wound around a core of the transformer; and a detection circuit detecting voltages of the first port and the third port by measuring a variation in a sense voltage generated by combining voltages of the first search coil and the second search coil.
