説明

The miniaturization and higher efficiency performances of boost converter for Electric Vehicle have been required. In this paper, a novel recovery-less boost chopper circuit, which can reduce the power loss in diode and power switching devices, is presented. The proposed circuit is able to control recovery phenomenon by the additional inductor. Therefore, the current transition through the diodes is softly owing to the additional inductor. Furthermore zero current turn on soft switching operation can be achieved in active switching devices. The additional inductor is required best design to control diode recovery phenomenon. This paper describes the design method of additional inductor and transformer turn ratio. In the experimental results, controlling diode recovery and realizing zero current turn on soft switching operation is confirmed actually. As a result, the proposed circuit achieves 0.4% higher efficiency as compared with one of conventional circuit. As future trends, reverse buck topology is shown for regeneration aspect. In the simulation result, operation of the topology is confirmed.
