<P>PROBLEM TO BE SOLVED: To prevent heating that follows power conditioner dielectric breakdown and occurrence of high-frequency current caused by capacitance drop, even if the dielectric breakdown occurs at a film capacitor element constituting an output stage film capacitor structure of a power conditioner by a high voltage generated instantaneously by a lightening strike or the like close to the installation of the power conditioner. <P>SOLUTION: In the power conditioner, a film capacitor element 6A acting as a low-pass filter for cutting off high frequency that is generated by an inverter circuit 5 is provided between the inverter circuit 5 which converts a DC power of a power supply 1 to an AC power for outputting and an interconnection relay 7 for cutting off interconnection between the power supply 1 and a system supply 4. Here, the film capacitor element 6A is directly attached with a temperature fuse 16 for detecting temperature of the film capacitor element 6A. <P>COPYRIGHT: (C)2012,JPO&INPIT |
