通信手段を持つ適応誘導電源
Document Type and Number:
Japanese Patent JP6441883
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.
