ELECTRIC POWER SUPPLY APPARATUS, CONTACTLESS ELECTRICITY TRANSMISSION APPARATUS, VEHICLE, AND CONTACTLESS ELECTRIC POWER TRANSFER SYSTEM

摘要

An electric power supply apparatus includes a choke coil, a switching element, a resonance circuit and a compensation circuit. The parasitic capacitance of the switching element is larger than a predetermined capacitance needed for realizing class E zero-voltage switching. The compensation circuit is connected in parallel with the switching element. The compensation circuit includes a coil and a capacitor, and has inductive impedance.
