Title:
An adaptation guidance power supply with a means of communication
Document Type and Number:
Japanese Patent JP5986151
Kind Code:
B2
Abstract:
A contactless power supply for inductively providing power to a remote device comprising: a resonant circuit having at least one of a variable capacitor with a variable capacitance and a variable inductor with a variable inductance, said resonant circuit having a variable resonant frequency that varies as a function of said at least one of said variable capacitor and said variable inductor, said resonant circuit having a primary for transferring power to the remote device; circuitry for providing power at an operating frequency, rail voltage, and duty cycle; a receiver for receiving information from said remote device; a controller electrically coupled to said receiver and said circuitry, wherein said controller is programmed to: (1) vary said variable resonant frequency of said resonant circuit by at least one of (i) varying said capacitance of said variable capacitor of said resonant circuit; and (ii) varying said variable inductance of said variable inductor of said resonant circuit; and (2) vary at least one of said operating frequency, said duty cycle, and said rail voltage.
