STRUCTURE FOR OUTPUT-STAGE FILM CAPACITOR IN POWER CONDITIONER

摘要

The present invention has a film capacitor element (6A) as a low-pass filter for blocking off high-frequency waves generated by an inverter circuit (5), the film capacitor element being disposed between the inverter circuit (5) for converting the DC power of a power supply (1) to AC power and outputting the AC power, and an interlinking relay (7) for blocking interlinking connections between the power supply (1) and a system power supply (4). In this case, the temperature of the film capacitor element (6A) is detected by directly connecting a temperature fuse (16) to the film capacitor element (6A).
