ABSTRACT:
The highly efficient multi-frequency voltage regulating circuit is capable of converting magnetic field energy to electrical energy for charging either a battery or an energy storage device such as a capacitor. The invention provides a magnetic field sensor circuit that measures the strength of incoming magnetic field energy with respect to a reference current. The invention also provides for a programmable magnetic field detection circuit which is used to adjust the detection level of the inductor-capacitor magnetic field converter circuit. A discharge expediter circuit is provided to improve the efficiency of the magnetic field converter circuit by discharging excess energy.
