Outline of Final Research Achievements

In anticipation of the mass introduction era of household solar power generation system, we developed a fundamental technology for reducing the maintenance costs and for extending the service cycle time of the power conditioner which is essential for high-reliable power generation systems. Following outcomes was obtained; (1) the development of long-life power conditioner that does not use an electrolytic capacitor of reduced factor of the system life. (2) evaluation method and application technology of the power capacitors that is suitable for long life of the system, (3) optimal inductor design method essential for small and low loss of the power conditioner system. These achievements is expected to be used as key technology for realizing low-cost, small volume, and ultra-long lifetime of the power conditioner systems.
