Electronic circuit and system for wireless charging
First Claim
1. An electronic circuit for a portable battery-powered electronic device, the electronic circuit being operable in a first mode as an actuator and in a second mode as a wireless charging receiver;
- wherein the electronic circuit comprises;
an electromechanical actuator comprising an inductor;
a capacitance selectively connectable to the inductor, at least in the second mode, to form therewith a resonant circuit for inductively receiving an electromagnetic wireless charging signal; and
a multi-mode switching circuitry comprising one or more switching devices for switching the electronic circuit between its different modes, at least one of the switching devices being configurable as a rectifying device, wherein;
in the first mode, the switching circuitry is configured to connect the actuator to an electrical power input of the electronic circuit; and
in the second mode, the switching circuitry is configured as a rectifier circuit for rectifying a voltage induced in the resonant circuit in response to a received electromagnetic wireless charging signal and for providing the rectified voltage at a power output of the electronic circuit as a charging voltage for a battery of the portable electronic device, wherein said at least one configurable switching device is configured as a rectifying device of the rectifier circuit.
