Design of Modular 110V / 370V 10kW Front-End Converter for High-Power Single-Phase Inverter

In this paper, design of a modular 110–370 Vdc 60 kW DC-DC front-end converter for industrial single-phase inverter using 10kW modules is presented. Main reasons for application of front-end converter are described and basic rules for its design are shown. Architecture of the converter is presented and details in realization of a single module are given. Finally, the most important results of a single module testing are presented to verify the capability to support the expected operating conditions.
