PROBLEM TO BE SOLVED: To provide a power conditioner that can enhance the heat radiation performance and avoid increase of the size of a case.SOLUTION: A power conditioner includes a case 3 comprising a case body 1 and a panel 2, and an electronic circuit block B1 which is housed in the case 3 and performs at least a system interconnection operation between a solar battery A1 and a commercial electric power system. The electronic circuit block B1 has at least a booster circuit for boosting a DC voltage from the solar battery A1, a capacitor C1, and an inverter circuit for converting a DC voltage to an AC voltage. A capacitor C1 is disposed between a switching element Q1 of the boosting circuit and a switching element Q2 of the inverter circuit, and the switching element Q1 of the boosting circuit and the switching element Q2 of the inverter circuit are mounted on a common heat sink 7.SELECTED DRAWING: Figure 1 |
