SINGLE-SENSOR MICROCONTROLLER-BASED APPROACH FOR GROUND FAULT CIRCUIT INTERRUPTERS

摘要

A microcontroller-based temperature compensated circuit for ground-faultcircuit interrupter to meet the requirements of UL 943 using a single sensorto detect both ground-fault and grounded-neutral fault conditions in both full-wave and half-wave AC power supplies as part of a ground-fault circuit breakeror a receptacle device.
