The Research And Application Of Series Resonance Converter In Contactless Electrical Power Deliver Technology

This paper presents a contactless electrical power deliver technology in the first place. It's a novel inductive electrical power deliver that deliver power from stillness apparatus to moving electrical apparatus. This technology is based on power electronics and electromagnetic induction, and realized by applying modern control theory. In this paper, to reduce the volume and weight of the system, this system employs high-frequency converting technology. Because of no contact and friction, damage to the apparatus may be decreased and the spark may be ignited will disappear. Potential applications are the rising power delivery for high-speed electric locomotive and electric vehicle. It can also be applied to chemical industry, mining and other inflammable fields.In the next place, the paper analyses systematically high frequency coaxial winding transformer applied to the load of series resonance converter, puts up its mathematical model, and presents a optimum design.In the end, by studying the load character of contactless electrical power deliver system, this paper designs the high frequency full-bridge series resonance converter. This paper analyzes the operating principle of converter in detail, and designs the main circuit and the controlling circuit of the series resonance converter. According to the design of converter, it makes simulation and experiment. As a result, it's proved that this design project of converter is viable.
