Abstract
Active rectification with load impedance switching for communication across a pulse transformer is presented. Load impedance switching is used for communicating data from the secondary side of the transformer to the primary side during data frames. During power frames, the load impedance is switched to a capacitor for the storage of charge from received power pulses, which may then be converted into a power source. The active rectifier circuit is configurable to accommodate different power requirements and transformer characteristics, and may be implemented with half-wave or full-wave configurations. In active mode, switches are enabled to short out diodes such that diode voltage losses are overcome in the recovered power supply voltage.
