摘要： A voltage boost converter (ES6) includes: a main voltage boost portion (LN1) that has a first switch (El) and a first coil (LI), and that raises output voltage of a direct - current power source (FC) by using counter electromotive force of the coil caused by the switch performing a switching action on the coil; and a subsidiary voltage boost portion (LN2) which has a capacitor (C2) that adjusts potential difference between two poles of the switch by amount of electricity stored, and which reduces switching loss of the switch by adjusting the amount of electricity in the capacitor during the switching action, and which has a second switch (E2) and a second coil. The second coil is formed by winding a wire around at least a portion of a core formed of a magnetic body. The core is provided with a gap formed of a non-magnetic body. A core region formed of a magnetic body is adjacent to the gap.
