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.
摘要翻译：控制启动技术可以通过控制电气设备的速度来消除过高的峰值结温。较低的速度可能会降低负载的功率。降低功率可能导致损耗降低，以维持可靠的工作结温。一旦结点达到预定的温度极限，可以控制速度以保持结温恒定。随着时间的推移，冷却液温度可能会降低，从而允许更高的功率水平，而不会增加IGBT的温度。不同于常规方法，可能在启动时连续地允许全功率，从而可能导致高温关闭状态或需要额外的热惯性来处理由于连续全功率启动而导致的高热负荷，受控启动消除了对广泛热增强的设计处罚，以适应偶尔的极热启动。
