Abstract
A high-speed current sensing circuit configured to measure current associated with switching devices of a power generation system. The circuit includes logic for turning one or more corresponding switching devices off before failure, so as to limit the duty cycle of the one or more corresponding switching devices. In the event of a failure, the system is configured to continue operating and generating energy to complete or at least continue performing the service despite the failure.
