摘要： Methods, systems, and devices for controlling a variable capacitor. One aspect features a variable capacitance device that includes a capacitor C1), a first transistor (M1), a second transistor (M2), and control circuitry. The control circuitry is configured to adjust an effective capacitance of the capacitor by performing operations including detecting a zero-crossing of an input current (I1) at a first time. Switching off the first transistor. Estimating a first delay period for switching the first transistor on when a voltage across the capacitor is zero. Switching on the first transistor after the first delay period from the first time. Detecting a zero-crossing of the input current at a second time. Switching off the second transistor. Estimating a second delay period for switching the second transistor on when a voltage across the capacitor is zero. Switching on the second transistor after the second delay period from the second time.

摘要： Described herein are improved configurations for a wireless power transfer. Described are methods and designs for implantable electronics and devices. Wireless energy transfer is utilized to eliminate cords and power cables puncturing the skin to power an implantable device. Repeater resonators are employed to improve the power transfer characteristics between the source and the device resonators.
