A new high frequency current generation method for inductive power transfer applications

摘要: This paper proposes a new method to generate high frequency currents for inductive power transfer systems where AC-DC-AC or DC-AC converters are being used. There lot of circuit and controller design issues associated with these traditional converters. A DC link has be used as middle stage current generation even when low AC source is available, which causes large system cost, size, well losses maintenance associated. Unlike matrix having complicated switching topologies control, the converter proposed in this based on simply free oscillation energy injection control. It can achieve inversion, direct conversion without using any links, thus utility at 50/60Hz converted along track loop directly. Furthermore, soft techniques applied minimize EMI, magnitude controlled easily overshoots. Theoretical analysis, simulation experimental results have demonstrated converting valid most systems.
