PROBLEM TO BE SOLVED: To provide a power conditioner device which stops a system surely and safely when abnormal heat generation of a terminal block which is caused by aging deterioration and insufficient screw-fastening in the terminal block occurs and when abnormal heat generation of a film capacitor in a filter circuit which is caused by lightening surge or the like occurs, and which allows a user to be notified of occurrence of abnormalities.SOLUTION: In the present invention, power for gate driver driving for transmitting a switching signal to a semiconductor switching element which constitutes a DC-DC converter and a system-connection inverter is supplied to a gate driver through a temperature fuse installed in a terminal block, and rear-stage power/voltage for gate driver driving of the temperature fuse is input in detection means, such as a microcomputer. Moreover, the temperature fuse is connected in series to the film capacitor of a filter circuit to thermally connect them. |
