Current control in high-efficiency unidirectional converter for fuel cell

Abstract:

This paper presents a model to implement the switching technique of a novel isolated DC/DC converter of full-bridge to link fuel cell power output to the distribution system. The implementation was performed on a DSP F2812 of Texas Instruments. It is also proposed a new start-up system (software), to avoid overcurrent on the input side of inverter. This software avoids using an auxiliary circuit for start-up, so reducing costs, improving volume and weight and maintaining the same efficiency. A prototype has been implemented to validate the performance. Finally, comparative experimental results are presented.
