A bidirectional DC-DC converter for renewable energy systems 


 

P1--A bidirectional DC-DC converter for renewable energy systems

Abstract. To improve the energy quality, most of the renewable energy systems include an energy storage element charged by the bidirectional DC-DC converter. This paper proposes the bidirectional DC-DC converter which employs the two bridge configuration resonant class-E converters on the both sides of the isolating transformer. The low side converter is controlled as step up and the high side converter is controlled as step down. The proposed system is characterized by good dynamic properties and high efficiency because the converter transistors are switched in ZVS conditions. A theoretical analysis to provide relations for system design, and the laboratory model investigations to validate the system characteristic are given in the paper.

Key words: bidirectional, isolated, energy storage system, DC-DC converter.
