Power Conditioner Consisting of Utility Interactive Inverter and Soft-Switching DC-DC Converter for Fuel-Cell Cogeneration System

Renewable energy has been a great concern to obtain ecological society that can continuously grow. As an hopeful solution, the fuel cell cogeneration system has been attracted and some first products have been developed in Japan and in some other centuries/areas. A product in Japan, which is the first developed system and hundreds of the sets are under operation in homes, has been investigated The novel topology consisting of a high-frequency transformer isolated soft-switching DC-DC converter and a utility interactive PWM inverter is practically evaluated.
