Design and Implementation of Current–Fed Boost Converter Using Fuel Cell Concept

G. Balasundaram, C. Dinakaran

Abstract :

– This paper concentrates on a three–phase dc/dc converter with high efficiency and voltage boosting capability designed for use in the interface between minimum voltage fuel cell concept and it is also used for high voltage dc bus for inverters. Zero–voltage switching in all active switches is achieved through using a common active clamp anch and zero current switching in the rectifier diodes is achieved through discontinuous current conduction in the secondary side. The converter is capable of increased power transfer due to its three–phase power configuration. It reduces the RMS current per phase and reduces conduction losses. A delta–delta connection on the three–phase transformer provides parallel current paths and reduces conduction losses in the transformer windings. An efficiency of above 93% is achieved through both improvements in the switching and through reducing conduction losses. A high voltage ratio is achieved by combining inherent voltage boost characteristics of the current–fed converter and the transformer turns ratio. The proposed converter, a three–phase PWM strategy and fuel cell concept is simulated.
