| Popis: | Wireless power transfer (WPT) for moving electric vehicles has been widely studied. LCC topology was proposed as a novel compensation circuit for dynamic WPT (DWPT) because inverter current is suppressed automatically according to the decrease in coupling coefficient. In addition, its characteristic enables a DWPT system to connect multiple transmitter coils to a single inverter. This paper proposed an optimal load condition under a multi-parallel operation considering waiting loss. Moreover, two types of LCC topologies are approximated into a Series-Series compensation topology, and the effective range of that approximation is derived. Calculation results revealed the effective range of the approximation. The proposed method improved transmission efficiency by up to 7% in the experiment. |
