摘要： The present invention locates the primary winding (12) of a transformer in a configuration where it substantially surrounds the secondary winding (20) of the transformer in order to enhance the efficiency of the electromagnetic coupling. High magnetic permeability material (14) surrounds portions of the primary winding (12) of the transformer. The transformer is designed to efficiently operate at frequencies of approximately 50 kilohertz. In one preferred embodiment, the primary winding (12) of the invention is formed of two U-shapes in which the parallel members of the U are substantially longer than the bottom portion of the U. The two U-shapes form a rectangular shape and the substantially parallel rectangular portions are surrounded by high magnetic permeability material (14) to further enhance the electromagnetic coupling between the primary winding (12) and the secondary winding (20).

摘要： The present invention converts an alternating current input (V1 - V3) into a direct current output by switching a current load at high speeds to create a voltage envelope having a maximum allowed voltage and a minimum allowed voltage. Complementary switching elements (300-310) are employed to take advantage of both the positive and negative portions of an AC cycle. Load switching is arranged so that the current vector which represents the load is nearly coincident with the voltage vector which represents the power source. The system can operate in an open loop mode at a constant frequency, in a closed loop mode, or in a hysteresis mode. During open loop operation, the voltage envelope is not rigidly defined as the switching frequency remains constant. During hysteresis mode control, the voltage envelope remains fixed and the current switching frequency varies.
摘要翻译：本发明通过以高速切换电流负载来将交流输入（V1-V3）转换为直流输出，以产生具有最大允许电压和最小允许电压的电压包络。采用互补开关元件（300-310）来利用AC循环的正和负部分。布置负载切换，使得表示负载的电流矢量几乎与表示电源的电压矢量一致。该系统可以在恒定频率，闭环模式或迟滞模式下以开环模式工作。在开环工作期间，开关频率保持恒定，电压包络不是刚性定义的。在滞后模式控制期间，电压包络保持固定，电流开关频率变化。

摘要： A power conversion system is described which includes a power input (514-518) for accepting a waveform at a given power level and frequency, and a power output (534, 536, 540, 542, 552 and 554) for providing an output waveform at a second given power level. A DC to AC converter (524) accepts a waveform based on an input wave form from the power input and converts the waveform to an AC waveform having a frequency at least approximately an order of magnitude higher than the frequency of the input waveform for application to an AC to DC converter (532 and 538) output. An AC converter (550) accepts the output waveform from the DC to AC converter output and provides a converted waveform from an output of the AC converter to the power output. A coupling device (574) operates at the frequency of the converter output for coupling the output of the DC to AC converter to the AC converter.
