SISTEMA ELECTRONICO PARA EXCITAR UNA CARGA INDUCTIVA CON CONTROL DEL ESTADO DEL PROPIO CIRCUITO DE CARGA.

摘要

A testable load driving circuit apparatus includes a solid-state load driver for controlling AC current loads coupled in series with a winding of a saturable core reactor used for sensing the presence or absence of load current through a load current monitor which is coupled to another winding in the reactor. The load driving circuitry may be tested during circuit operation by injecting a signal of insufficient duration to substantially affect the load circuit.
