RESONANCE-TYPE ELECTRICAL POWER-TRANSMITTING DEVICE

摘要

The present invention is provided with: resonance-type power source circuits 11 for at least two electrical grids, said circuits 11 being provided with a power element for conducting switching operations at a high frequency of 2 MHz or greater, and a resonance circuit element for causing the power element to perform a resonance switching operation; a phase-control-type matching circuit 12 provided to each of the electrical grids, the phase-control-type matching circuit 12 having a function for controlling the phase difference in the output current between the resonance-type power source circuits 11 and a function for harmonizing resonance conditions between the resonance-type power source circuits 11 and a load; and a synthesizing unit 13 for synthesizing the output electric current processed using the phase-control-type matching circuit 12 for each electrical grid.
