SYSTEM AND METHOD FOR POWERING A LOAD

摘要

A power supply for inductively powering a remote device has an inverter operating at an operating frequency and a primary coil, A phase comparator compares the phase of the voltage or current delivered by the power supply. If the phase relationship detected by the comparator is unacceptable, the inverter is disabled. After a period of time, the inverter is re-enabled, an d the phase relationship is again determined.
