Abstract :
Nowadays, applications of DC-AC inverters in various applications such as hybrid electric vehicles are growing up. DC-DC converters are one of the important parts of the HEVs. Dual output DC-AC inverters can be used in them. If a multi input-multi output inverter be used, then the DC-DC converter should be able to prepare the inputs for that. This paper proposes a new bi-directional DC/DC converter. It can be used as a single input single output or single input multi output device. Also, it can be used as an isolated circuit by replacing the inductance in the input side, which is parallel with the input source, with a transformer. This topology can conduct the input current in both direct and reverse directions. In addition, the close loop controller design for the non-isolated DC-DC converter is discussed in detail. Also it´s parameters values has been designed. In order to validate the performance of proposed topology, simulation and also experimental results are presented.
