摘要： A high efficiency power conversion at high frequencies with zero voltage switching is obtained by using magnetizing current of a transformer or parallel inductance to charge the switch adjunct capacitance and other capacitance during the dead time. A transformer is prevented from being loaded during the dead time. Loading of the transformer during the dead time is prevented by directing the output inertial current to a capacitor instead of through the rectifiers to the secondary of the transformer. This can also be achieved by using synchronized rectification that provides pulse width modulated regulation on the output and ensures that the transformer secondary is separated from the inertial current of the output during the dead time. Voltage and current stresses on the switching devices and rectifiers are minimized. Zero voltage switching may be applied to inverters where the load is resistive.

摘要： An inverter with galvanic separation including a resonant converter and an upstream mounted boost chopper is intended to provide galvanic separation in the context of a variable input and output voltage as it exists in photovoltaic systems, with the efficiency being intended to be optimized over the entire input voltage range. This is achieved in that a boost chopper or a buck chopper is mounted upstream of the resonant converter.

摘要： A battery-operated motor system includes a rechargeable battery, a motor and circuitry for recharging the battery. The recharging circuit processes externally applied energy to provide a source of recharging current. The recharging current is applied to a winding in the motor in the form of periodic current pulses. Following each pulse, energy thus stored in the motor winding is allowed to discharge into the battery, thereby recharging it. Use of the motor winding in this manner avoids the need to provide a separate inductance for recharging the battery and results in reduced weight, fewer components and greater manufacturing economy. The large inductance of the motor winding also enables recharging at a rate well suited to the particular motor/battery combination. By using existing components of a known H bridge motor drive to perform the various switching functions, further savings in these areas can be realized.

摘要： There is disclosed a small-sized RF high-voltage power supply capable of stably supplying an RF high voltage to a load at the maximum power efficiency, even if the load has a nonlinear electrostatic capacity that varies with the applied voltage. The power supply has an RF step-up transformer equipped with a primary winding having a tap to which one end of a power capacitor is connected. An oscillating inductor, a thyristor, and the other end of the power capacitor are connected in series with each end of the primary winding in this order. Each thyristor conducts when a voltage is applied to it from the corresponding end of the primary winding. A diode is connected in antiparallel with each thyristor. The thyristors are alternately triggered to conducting state.

摘要： A power converter for operation with a d.c. power supply to provide an output voltage having a level controlled in response to an external control signal. The converter uses a dual chopper configuraton with the out of phase outputs from the respective chopper halves being combined in an interphase transformer. To prevent the interphase transformer from saturating, the chopper control includes an oscillator, counter, D/A converter and phase delay comparator arrangement for maintaining substantially identical duty cycles in the respective legs while, of course, allowing the duty cycles to be varied in unison. The interphase transformer is wound in a configuration which presents a magnetic shunt between the halves of the transformer, said shunt serving to limit transients which might be coupled to the chopper load.
