Abstract :
A high-frequency transformer isolated soft-switching DC-DC converter for fuel-cell cogeneration systems with utility-interactive inverter is investigated. The new type DC-DC converter offers a high efficiency in a wide power range, from rated to low power, by means of a new soft-switching topology. A prototype of the DC-DC converter and utility-interactive inverter cascade system is practically evaluated to confirm the fine performance
