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.

A control arrangement and method is provided for electronic devices in which an electronic switch is maintained in a conducting state at all times other than when it is desired to render the electronic switch nonconducting. In a specific embodiment, a latched control signal is utilized which is changed by the receipt of a momentary signal to change the conducting state of the electronic switch. For example, according to one specific arrangement, the momentary signal is a secure, complex signal such that appropriate decoding and detection of the proper signal is required to change the conducting state of the electronic switch.

A fault interrupting and reclosing device includes a circuit interrupter coupled to an actuator. The actuator includes at least one force generating element for generating an opening force for opening the circuit interrupter and for generating a restoring force to close the circuit interrupter. The device further includes a latch to engage the actuator to hold the contacts open once opened. In a preferred arrangement, the device is provided with an automatic mode of operation including a reclose process and a non-reclosing mode of operation. The device also preferably includes a method of determining the end-of-life of a vacuum interrupter monitors characteristics and/or parameters of a fault current or vacuum interrupter operation to predict a percent of life consumed with each fault current interruption operation. A cumulative percent of life consumed may also be determined, and an end-of-life may be predicted based upon the cumulative percent of life consumed.

An efficient configuration for a power system is provided, e. g. for high-speed source transfer, utilizing power electronic assemblies and a directed ventilation arrangement. Each power electronic assembly includes a plurality of stacked power electronic device modules that are electrically series connected and energized at various voltages. Each power electronic device module includes two heat sinks, a power electronic component assembly interposed between the two heat sinks, and an arrangement for clamping the heat sinks and the power electronic component assembly. In a preferred embodiment, the power electronic component assembly includes two stacked, series connected power electronic components such that single-sided cooling is provided. In one application, the power-electronic components are thyristors that have a high short-term, fault-current rating and a relatively low average current requirement. This arrangement provides a reduced height configuration along with the advantages of modular clamping for ease of assembly, simplicity of components, ease of maintenance and overall reliability of components.
