Abstract

The invention provides an amplitude limiting control circuit and method. The circuit comprises a resonance coil, a resonance capacitor, a switch and an inductor. The inductor is connected with the resonance coil in series after being connected with the switch in parallel to obtain a first circuit, and the first circuit is connected with the resonance capacitor in parallel or in series. When stable voltage needs to be provided, the switch is controlled to be switched on, the inductor is short-circuited, inductance of the circuit is changed, and the resonance state is further changed, stable voltage or current can be provided, and the problem that a driven resonance ring is instable in work is solved.

Description

technical field [0001] The present invention relates to the field of wireless power supply, and more specifically, relates to a limiter control circuit and method. Background technique [0002] The driven resonant ring has the dual characteristics of receiving energy and transmitting energy. In the wireless power supply terminal, the driven resonant ring is often used as a receiving resonant ring to supply power to terminal appliances. [0003] Since the driven resonant ring works in a resonant state, the voltage and current amplitude in the resonant ring is large and unstable. If the power is directly supplied to the terminal electrical appliances, huge current and voltage fluctuations will be generated, which will have a serious impact on the terminal electrical appliances. , and even burn electrical appliances. [0004] Therefore, there is an urgent need for a circuit that controls the voltage or current amplitude of the driven resonant ring to ensure stable operation of...
