摘要： A multi-level rectifier is presented that is suitable for use at high frequencies, including into MHz range such as in the 6.78 MHz band used for wireless power transfer. Depending on the amplitude of the input waveform, the rectifier can be operated in different modes. For lower input levels, the rectifier acts as a voltage doubler. For higher input levels, the impedance of the rectifier can be varied based on the input level. The rectifier is a synchronous rectifier with a front section and a back section, where the impedance is varied by changing the phase of the control signal of the back section relative to that of the front section.

摘要： The present disclosure describes aspects of in-body power harvesting using flowing fluids. In some aspects, an apparatus comprises a magnetic field generator configured to generate a magnetic field to deflect charged particles of a fluid flowing through the body in a space formed by a vessel. The charged particles include positively and negatively charged particles, which the magnetic field deflects such that the positively charged particles are deflected in a first direction within the space and such that the negatively charged particles are deflected in a second direction within the space generally opposing the first direction. The apparatus also includes electrodes configured to harvest energy based on a difference in potential between the positively charged particles and the negatively charged particles. The harvested energy is convertible by a converter coupled to the electrodes into electrical power that is usable by an electronic device.
