Abstract:
1. A boost converter comprising: a boost circuit including at least one switching element, a first terminal of the at least one switching element being electrically connected to a first inductor and a second terminal of the at least one switching element being electrically connected to a second inductor; a controller that turns on and off the at least one switching element to boost an input voltage of the boost circuit and output a boosted voltage; a thermally and electrically conductive mounting member mounting the at least one switching element thereon; a reference potential member that serves as a frame ground for the boost circuit, the reference potential member being coupled to the mounting member with an insulator therebetween, wherein a first floating capacitor is formed between a first electrical path and the mounting member, the first electrical path being at the same potential as a junction between the at least one switching element and the first inductor; and a second floating capacitor is formed between a second electrical path and the mounting member, the second electrical path being at the same potential as a junction between the at least one switching element and the second inductor.
