    摘要: An autotransformer for use in low frequency, high power applications that uses a stack of printed wire boards constructed of a top, inner, and bottom layer including electrical trace windings circumventing the transformer core and formed in the inner layer for direct thermal contact with a heat sink interface providing a uniform and consistent heat path down to the heat sink plate. The autotransformer further includes a board to board connection employing solder cups to electrically connect between predetermined printed wire board traces. The printed wire board autotransformer also may use a non-planar interface for thermal interface with a non-planar heat sink plate surface.

    摘要: An integral cold plate/chassis (ICPC) housing may be formed from two blocks of material, having a cold plate sandwiched therebetween, brazed together. The blocks may then be machined to fit power electronics therein, thereby providing a cold plate as an integral part of the power electronic's housing. Unlike conventional heat exchangers that may be used to dissipate heat from power-dissipating components that are housed typically in sheet metal housings, the ICPC described herein provides a cold plate integral to the housing of power electronics, thereby allowing the rapid and efficient removal of heat from the components into the cold plate carrier fluid and out of the system.

    摘要: A controlled start up technique may eliminate the excessive peak junction temperature by controlling the speed of the electric device. Lower speed may result in reduced power to the load. Reduced power may result in reduced losses to maintain reliable operating junction temperatures. Once the junction reaches the predetermined temperature limit, speed may be controlled to hold the junction temperature constant. As time elapses, the coolant temperature may reduce, thereby allowing a higher power level without an increase in IGBT temperature. Unlike conventional methods which may allow for full power continuously upon start up, thereby either potentially causing a high temperature shut-down condition or requiring additional thermal inertia to handle a high heat load due to a continuous full-power start up, the controlled start up eliminates the design penalties for extensive thermal enhancements to accommodate the occasional extreme hot start up.
