摘要： A logic circuit is driven by a single alternating voltage power supply so that the energy stored in parasitic capacitances can be mostly recovered, rather than dissipated, as in conventional logic designs. Successive stages of the logic circuit are of opposite conductivity types such that the successive stages are activated in alternate half cycles of the power supply without separate clock signals. Each stage of the logic circuit is precharged during a respective first half cycle of the power supply and is active in logical processing during a second half cycle. The half cycles are defined by the rising and falling edges of the power supply. The logic circuit resonates with an inductor coupled across the power supply but closely coupled to the logic circuit. This inductor and the method of charging and discharging the capacitors in the logic circuit serve to minimize the power dissipated during logical processing.
摘要翻译：逻辑电路由单个交流电压电源驱动，使得存储在寄生电容中的能量可以大部分被恢复，而不是耗散，如在常规逻辑设计中。逻辑电路的连续阶段具有相反的导电类型，使得连续级在电源的交替半周期中被激活，而没有单独的时钟信号。逻辑电路的每个级在电源的相应的第一半周期期间被预充电，并且在第二个半周期期间的逻辑处理中是有效的。半周期由电源的上升沿和下降沿决定。逻辑电路与耦合在电源上但紧密耦合到逻辑电路的电感谐振。该电感器和对逻辑电路中的电容器进行充电和放电的方法用于使逻辑处理期间的功耗最小化。

摘要： A power semiconductor device which comprises either a bipolar transistor or a MOSFET, incorporates an integral Schottky diode in antiparallel connection with the transistor for conducting reverse current through the power semiconductor device. By fabricating the diode to exhibit a lower turn-on voltage, than the P-N junction at the base and collector interface in the bipolar transistor, or at the base and drift layer interface in the MOSFET, the power semiconductor device, when in the reverse conduction mode, exhibits excellent reverse recovery characteristics and without forward voltage overshoot transients.

摘要： A dc-dc converter system comprises a quasi-regulated bus converter and plural regulation stages that regulate the output of the bus converter. The bus converter has at least one controlled rectifier with a parallel uncontrolled rectifier. A control circuit controls the controlled rectifier to cause a normally non-regulated mode of operation through a portion of an operating range of source voltage and a regulated output during another portion. The bus converter may be an isolation stage having primary and secondary transformer winding circuits. For the non-regulated output, each primary winding has a voltage waveform with a fixed duty cycle. The fixed duty cycle causes substantially uninterrupted flow of power during non-regulated operation. Inductors at the bus converter input and in a filter at the output of the bus converter may saturate during non-regulated operation.

摘要： A power converter nearly losslessly delivers energy and recovers energy from capacitors associated with controlled rectifiers in a secondary winding circuit, each controlled rectifier having a parallel uncontrolled rectifier. First and second primary switches in series with first and second primary windings, respectively, are turned on for a fixed duty cycle, each for approximately one half of the switching cycle. Switched transition times are short relative to the on-state and off-state times of the controlled rectifiers. The control inputs to the controlled rectifiers are cross-coupled from opposite secondary transformer windings.

摘要： In a power converter, the duty cycle of a primary winding circuit causes near continuous flow of power through the primary and secondary winding circuits during normal operation. By providing no regulation during normal operation, a very efficient circuit is obtained with a synchronous rectifier in the secondary operating at all times. However, during certain conditions such as start up or a short-circuit, the duty cycle of the primary may be reduced to cause freewheeling periods. A normally non-regulating isolation stage may be followed by plural non-isolating regulation stages. To simplify the gate drive, the synchronous rectifiers may be allowed to turn off for a portion of the cycle when the duty cycle is reduced. A filter inductance of the secondary winding circuit is sufficient to minimize ripple during normal operation, but allows large ripple when the duty cycle is reduced. By accepting large ripple during other than normal operation, a smaller filter inductance can be used.
