Recently, in photovoltaic power-generation systems continuing the rapid-high growth,DC voltage power-generated by solar-cell modules is converted to AC voltage (available for home-use) through inverter power-supplies called “ power conditioner ”. In these power conditioners, a lot of capacitors are used as noise-removing filters and DC smoothing circuits. We have been mass-producing the film capacitors for inverters HEV/EV and received high appreciation from the market, and have commercialized the film capacitors for power electronics, featuring long life and high safety, and will commence mass-production.
