RECTIFIER CIRCUIT FOR USE IN HIGH-FREQUENCY POWER SOURCE

摘要

This rectifier circuit for use in a high-frequency power source rectifies high-frequency AC voltages of 2MHz or higher, and is provided with: a class E rectifier circuit which rectifies an AC voltage inputted from a resonant receiver antenna (10); a resonance circuit which uses resonant switching for switching operations during rectification by the class E rectifier circuit; a matching function circuit that has a function for matching the resonance conditions with the resonant receiving antenna (10) and a function for matching the resonance conditions with the resonance circuit; and a smoothing function circuit which smoothes the voltage rectified by the class E rectifier circuit to a DC voltage.
