摘要： A power transmitter device of a non-contact power feeding device includes a transmitter coil configured to supply power to the power receiver device, a power supply circuit including a plurality of switching elements connected between a DC power supply and the transmitter coil in a full-bridge configuration or a half-bridge configuration. The power supply circuit may be configured to switch the plurality of switching elements to an on or off state at a switching frequency to convert DC power supplied from the DC power supply into AC power having the switching frequency and supply the AC power to the transmitter coil, and a phase control circuit including at least one LC series circuit connected to both ends of the transmitter coil.
