中文摘要:
      针对无尾果蔬机在使用过程中电机负载不断剧烈变化容易造成单管感应耦合电能传输ICPT(inductively coupled power transfer)系统中开关管和副边整流管损坏等问题,系统研究了单管逆变ICPT系统拓扑及其并联-并联PP(parallel-parallel)和并联-串联PS(parallel-series)补偿网络电路特性。通过建立数学模型,分别分析了PP和PS补偿网络各个参数间的关系,给出了其对应的电压增益和输出电压特性曲线;并用电路仿真软件分别对PP、PS系统在负载动态切换时的开关管耐压与输出电压波形进行了仿真。分别搭建了PP和PS补偿下额定输出功率为1 kW的单管逆变ICPT系统样机,对理论分析和仿真结果进行了实验验证。
英文摘要:
      The motor load of a wireless juicer changes constantly and remarkably during its operation, which easily causes damage to switches and secondary rectifiers in the single-tube inductively coupled power transfer(ICPT) system. In this paper, the topology of a single-tube inverter ICPT system and the characteristics of parallel-parallel(PP) and parallel-series(PS) compensation networks were studied. The relations among parameters of the PP and PS compensation networks were analyzed by establishing mathematical models, and the corresponding characteristic curves of voltage gain and output voltage were given, respectively; the waveforms of switch voltage and output voltage during dynamic load switching of the PP and PS systems were also simulated using the circuit simulation software. Two 1 kW prototypes of single-tube inverter ICPT system with PP and PS compensation networks were designed respectively, and the theoretical analysis and simulation results were validated through experiments.
