Non-contact power supply system utilizing synchronized command signals to control and correct phase differences amongst power supply units
Abstract:
A non-contact power supply system is provided in which current phases of induction lines are matched. According to the output current of a power supply unit (21) and the power consumption of induction lines (19), a lead time corresponding to a phase difference between the output currents of the induction lines is determined. A signal for driving transistors (52) is advanced ahead of a drive synchronization signal (β) according to the lead time.
Abstract(Chinese):

提供了一种非接触式电源系统，其中感应线的当前阶段相匹配。 根据电源单元（21）的输出电流和感应线（19）的功耗，确定与感应线的输出电流之间的相位差对应的提前时间。 用于驱动晶体管（52）的信号根据提前时间提前于驱动同步信号（＆bgr）。
