Zusammenfassung:	Provided is a power conversion circuit in which radiation noise is reduced. A power conversion circuit is provided with at least: a switching element (5) that opens and closes an input voltage via a reactor (4); and a commutation diode (7) that conducts a current flowing in the direction of an electromotive force generated from the reactor (4) when the switching element (5) is turned off by a voltage including at least the electromotive force, the commutation diode (7) including a gallium oxide Schottky barrier diode. 提供一种降低了辐射噪声的功率转换电路。功率转换电路至少具备：开关元件(5)，经由电抗器(4)对所输入的电压进行开闭；以及换向二极管(7)，通过至少包括在所述开关元件(5)关断时从所述电抗器(4)产生的电动势的电压，使沿所述电动势的方向流动的电流导通，所述换向二极管(7)包括氧化镓系肖特基势垒二极管。
