In the wireless power transfer system, the front stage power supply is used to efficiently transfer power to the post-stage circuit. As a bridge connecting the front stage power supply and the rear stage circuit of the wireless power transmission system, power converter network is generally placed behind the inverter so as to achieve output filtering of inverter and stability of output voltage and current. This paper analyses the LCC (inductance-capacitance-capacitance) and LCL (inductance-capacitance-inductance) transform network circuit model, and transmission characteristics of LCC and LCL conversion networks are analysed and compared based on two different circuit topologies. By means of parameter calculation, simulation analysis, and parameter optimisation design, it is concluded that both LCC and LCL networks have different characteristics. The results show that for both LCC and LCL network topologies, when the parameters of network components satisfy certain conditions, they can relatively achieve stable voltage or current output within a certain load range to meet the specific power transmission requirements. more...
