| Abstract: | It is known that the resonant operation of the coupled coils has important influences to reduce the reactive power and improve the transmission efficiency from the features of the resonant coupling circuit in the contractless power transmission(CPT) system.Based on above theory,a resonant frequency tracking method was presented in the CPT system by a DSP TMS320F2812 based software phase locked loop,and then the specific designing ideas and software flowcharts were introduced.Finally,the experimental results demonstrate the feasibility and effectiveness of this method. |
