RECTIFIER STABILITY ENHANCEMENT USING CLOSED LOOP CONTROL

A system and method for monitoring signal quality metrics coupled with closed-loop control improves rectifier signal quality and stability. The closed-loop control passes the metric through a high-pass filter and captures error values. This signal is then passed to a controller to adjust rectifier settings. The measured signal, where signal quality is derived could be V, F, network coil measurements, is used for ASK demodulation, or the like. The controller identifies noise levels and noise types in real-time, and sets parameters of the rectifier to preserve system stability. The controller may set baud rates and preamble thresholds in a wireless power transfer system in response to identified noise levels and types.
