Although the MC-WPT system based on PT symmetry has been proved to be a promising WPT system due to its characteristics of constant output power, constant transfer efficiency, constant voltage, and constant current, the system performances are limited by PT-symmetric range, switching frequency, switching loss, single-phase power supply, and so on.

摘要

Although the MC-WPT system based on PT symmetry has been proved to be a promising WPT system due to its characteristics of constant output power, constant transfer efficiency, constant voltage, and constant current, the system performances are limited by PT-symmetric range, switching frequency, switching loss, single-phase power supply, and so on.
