Abstract

A heat sink (11) comprised of a first heat dissipation portion (11a), a second heat dissipation portion (11b), and a third heat dissipation portion (11c) is mounted on a circuit board (14). Two sets of an inductor (L1, L2) that constitute an interleaved power factor correction circuit are arranged in a spatial region formed in the inside of the heat sink and are mounted on the circuit board. Two sets of a transistor (Tr1, Tr2) and a diode (D1, D2) that constitute the interleaved power factor correction circuit are attached to an outer surface of the first heat dissipation portion and are mounted on the circuit board. <img class="EMIRef" id="131196836-iaf01" />
