摘要： A power converter 2, which uses semiconductors such as thyristors to switch the AC supply at various phase angles to supply power to a load 1 generates lagging reactive power which is a disadvantage from several points of view. For this reason, a capacitor 3, which generates leading reactive power is provided to counteract the lagging reactive power, but this then has the effect of generating the leading reactive power when the load 1 is disconnected by opening of switch 8. To overcome the problems that this will cause in terms of the supply, a switch 8 is provided to enable an inductor 21 to be connected in parallel with the load, and the power converter is controlled so that the leading reactive power of the capacitor is now counteracted by the lagging reactive power of the inductor 21. In addition to converters 2 which convert AC to DC, the invention is also applicable to power converters which convert AC to AC and AC to DC and back to AC.
摘要翻译：使用诸如晶闸管之类的半导体的功率转换器2以各种相位角切换AC电源以向负载1供电以产生滞后无功功率，这在几个观点上是不利的。因此，提供产生前导无功功率的电容器3以抵消滞后无功功率，但是当负载1通过开关8断开而断开时，产生无功功率的效果。为了克服问题这将导致在供电方面，提供开关8以使得电感器21能够与负载并联连接，并且功率转换器被控制，使得电容器的前导无功功率现在被滞后电感器21的无功功率。除了将AC转换为DC的转换器2之外，本发明还可应用于将AC转换成AC和AC至DC并返回到AC的电力转换器。

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 voltage source converter includes a number of valves, the valves including switching elements with anti-parallel diodes provided in a bridge for switching between two states. The bridge is provided in at least one phase leg that stretches between two direct current poles and has at least one midpoint, which is connected to an alternating current terminal. The switching element of at least one valve is a thyristor. The converter further includes a commutation cell associated with the valve, where the commutation cell is controllable to reverse-bias the valve if it is to stop conducting current.
