Abstract:
      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.
