Abstract
A control arrangement and method is provided that monitors the condition and operating parameters of a power electronic system having power electronic devices and responds to various detected abnormalities via appropriate action to optimize operation of the power electronic system. The arrangement increases reliability of operation and optimizes the continuous supply of power to a load. For example, the arrangement responds to an overheated power electronic switch by switching to an alternate power electronic switch, the overheated power electronic switch being made available as a temporary alternate path. The arrangement also includes the capability for diagnosing the power electronic switches by measuring the temperature of the power electronics switches and communicating the temperature information in a coordinated fashion with information regarding the operating status of the power electronics switches. Additionally, shorted power electronic switches are detected and appropriate action taken.
