摘要： Overspeed protection of sensorless electric drives is needed in the aerospace industry. Methods for overspeed protection may include software implementations, hardware implementations or combinations thereof. Typical high-speed rotating machinery is designed to sustain overspeed operation of up to 50% beyond maximum normal operation. This requirement leads to substantial penalties in weight and volume. The methods of the present invention may allow for an opportunity to reduce this overspeed design to about 5 to 15%, typically about 7%.

摘要： A multiple-winding induction machine may be used to obtain a reduced-speed-variation electric drive when using a variable-frequency power distribution system. Each winding may have a different number of poles. The winding with the smallest number of poles may operate the machine at the lowest bus frequency, while the winding with the largest number of poles may operate the machine at the highest bus frequency. In one embodiment, a third winding, with a middle number of poles, may operate the machine at the middle frequency ranges. The speed of the induction machine is a function of the electrical frequency and the number of the winding poles. Therefore, the operating speed range can be reduced by switching from one winding to another. According to the present invention, windings with different numbers of poles can be designed to achieve different reductions in speed variation.

摘要： A power conversion system having a DC power distribution bus includes multiple power converters connected to the DC power distribution bus with modulation frequencies synchronized so that providing phase shifts between the different modulations has the effect of compensating voltage and current ripples, e.g., reducing voltage fluctuations, across the DC bus. Power conversion may be controlled using space vector modulation implemented, for example, by any of a variety of pulse width modulation schemes. Phase shifts in which nulls of the modulation cycles of different converters do not overlap (in the time domain) may be particularly effective for DC bus voltage ripple compensation. The novel method for DC bus voltage ripple compensation may be implemented by programming a digital signal processor to control the power converters.

摘要： A control system for an electrical power generation system (EPGS) provides overload protection without disconnecting a generator of the EPGS from an excessive electrical load. Available engine power and current levels of the electrical load are continuously measured. A command voltage is calculated that corresponds to a voltage required to sustain with the maximum available power. Output voltage of a generator of the EPGS is controlled at the calculated command voltage so that a power limit of the engine is not exceeded during electrical overload conditions.

摘要： Conventional electric power generation system employ a solid state electronically controlled IM that may be capable of self-start motoring and power generation, but, when the DC bus voltage collapses upon a failure, an additional external source of DC voltage is not available for IM excitation. The present invention provides an internal bus that does not collapse when the main DC bus is shorted. This internal or auxiliary bus may be used to excite the IM to provide generation function. The power generation systems of the present invention may play a significant role in the modern aerospace and military industries.

摘要： The present invention provides an apparatus and methods for providing constant voltage from a permanent magnet generator at varying prime mover speeds or under varying loads. A constant voltage permanent magnet generator includes a housing, a magnetized rotor, a prime mover operationally coupled with the rotor, a stator, a main winding coupled to the stator, and an excitation winding also coupled to the stator. A controllable three-phase inverter may be coupled to the excitation winding and a control system operationally coupled to the main winding for measuring the voltage of the main winding. The control system is further operationally coupled between the power source and the controllable three phase inverter to provide a supplemental current to the excitation winding such that a combined current through the main winding and the excitation winding produces a constant voltage from the generator.

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.
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。
