Abstract: A boost converter capable of reducing a common-mode current that flows to the outside of a casing. In the converter, a boost circuit includes first and second inductors and at least one switching element electrically connected therebetween. A controller turns on and off the at least one switching element to boost an input voltage of the boost circuit. A first floating capacitor is formed between a first electrical path, which is at the same potential as a junction between the at least one switching element and the first inductor, and a mounting member coupled to a reference potential member with an insulator therebetween. A second floating capacitor is formed between a second electrical path, which is at the same potential as a junction between the at least one switching element and the second inductor, and the mounting member.
