POWER CIRCUIT FOR NON-CONTACT POWER SUPPLY

摘要

PROBLEM TO BE SOLVED: To provide a power circuit which is capable of transmitting signals on low communication power in a non-contact power supply for use in power line carrier communication. SOLUTION: The output of a high-frequency inverter 100 input with commercial alternating-current power supply is led to a matching transformer 101, and thereafter a first resonance circuit comprising a capacitor 102 and a coil 103 is connected in parallel. Then a second resonance circuit comprising a capacitor 104 and a coil 105 is connected in series for configuring a power circuit for non-contact power supply.
