| Popis: | In this paper, characteristics of WPT systems based on CCL resonant circuit are investigated in consideration of parasitic resistances of circuit elements and a quantitative estimation method of power transfer performances of these systems is presented. Some adaptable calculation expressions are derived for the characteristics estimation of CCL resonant circuit and a remarkable feature of quality factor is observed in this circuit. A non-negligible impact of the parasitic resistances of circuit elements are investigated in CCL circuit and in WPT systems based on this circuit. Based on an equivalent system topology of CCL–CCL system, CCL-S system and S-CCL system, a quantitative performance estimation method of these systems is presented. The CCL circuit-based systems are estimated to have a great potential of realizing a high WPT performance, which is restricted by the rapid increase in total parasitic resistance that accompanies with the increase in quality factor. Experimental prototypes are constructed and the proposed theory is verified by the experimental results. |
