Power converter

Abstract

To provide a power conversion device that achieves miniaturization, low inductance, and reduced parasitic capacitance. [Solution] The multilayer wiring board comprises a first switching element and a second switching element electrically connected in series to constitute a first leg, a positive electrode wiring electrically connected to the first switching element, a negative electrode wiring electrically connected to the second switching element, and a first output wiring electrically connecting the first switching element and the second switching element, wherein the positive electrode wiring and the negative electrode wiring have a stacked wiring region stacked in the substrate thickness direction of the multilayer wiring board, the first switching element and the second switching element are arranged to overlap in the substrate thickness direction with the multilayer wiring board in between, and when viewed from the substrate thickness direction, the projected region where the first output wiring is arranged does not overlap with the projected region where the positive electrode wiring and the negative electrode wiring are arranged.
