Abstract

A voltage signal and a wetting current are received from a switching device. A first pulse train is created from the voltage signal and the first pulse train has a first duty cycle that is proportional to the voltage at the switching device. The first pulse train is transmitted across an isolation barrier. The first pulse train that is received across the isolation barrier is digitized and at least one operating condition of the switching device is determined based upon the digitized pulse train. A second pulse train having a second duty cycle is received and the wetting current from the switching device is controlled based upon the second duty cycle.
