摘要
从功率传输的角度出发,分析了非接触供电系统中并联调谐拾取电路和串联调谐拾取电路对系统参数和系统功率传输容量的影响。提出采用固定频率控制和动态无功参数调谐相结合的方法,以保证系统的工作频率恒定,并使开关器件工作在软开关状态。最后对改进后的系统进行了仿真研究和实验验证。
The influence that contactless power transfer (CPT) system in parallel resonance pick up circuit and series resonance pick-up circuit effects bring to system paramenters and system power transmission capacity are analyzed, according to the power transmission capacity. Fixed frequency control and dynamic resonance are presented to assure the system working frequency’s invariableness and the soft switch condition for the electrical devices. This result is validated by simulation and experiment.
