Title:
NONCONTACT POWER SUPPLY FACILITY
Document Type and Number:
WIPO Patent Application WO/2005/096485
Kind Code:
A1
Abstract:
A noncontact power supply facility in which current phase is matched between induction lines. According to the output current from a power supply device (21) and power consumption of an induction line (19), a lead time corresponding to the phase difference of output currents from the induction lines is determined and a signal for driving a transistor (52) is advanced ahead of a drive synchronization signal β depending on that lead time.
