Abstract
An electronic magnetic bearing fault-tolerant drive module includes a first plurality of switching elements and a second plurality of switching elements. At least one winding is interposed between the first plurality of switching elements and the second plurality of switching elements. The first and second switching elements are configured to selectively operate in a first mode and a second mode to generate an electromagnetic field. The electronic magnetic bearing fault-tolerant drive module is configured to detect one or more electrical faults including an open-circuit fault of at least one of the first and second switching elements.
