    摘要: A resonant power circuit which supplies pulsed power to a load, such as a pulsed laser, from a d.c. supply by cyclically charging a capacitor. The capacitor is discharged through the load on closure of a switch which should then open to allow the capacitor to re-charge. Occasionally the switch fails to open and the circuit of the invention then develops and applies a reverse voltage to the switch to force it to become an open circuit.

    摘要: A high-power switch network includes a laser fiber optically coupled to a network including light-initiated glow discharge switches in a Marx configuration. A low pressure gas source is used to replenish gas within the switches lost due to ionization. Each switch has a cylindrical insulating envelope with conductive end caps at each end. The end caps are electrically coupled, respectively, to a cup-shaped anode and a cup-shaped cathode. Apertures are formed centrally in closely spaced plates of the respective cup-shaped electrodes. Optical fiber cables extend through vacuum sealed ports of the switches so that the unfocused laser light is directed about the aperture of the cathode so as to close the switch, thus providing a high power output from the network.

    摘要: A high-power reversing-counterpulse repetitive-pulse inductive storage and transfer circuit includes an opening switch, a main energy storage coil, a counterpulse capacitor and a small inductor. After counterpulsing the opening switch off, the counterpulse capacitor is recharged by the main energy storage coil before the load pulse is initiated. This gives the counterpulse capacitor sufficient energy for the next counterpulse operation, although the polarity of the capacitor's voltage must be reversed before that can occur. By using a current-zero switch as the counterpulse start switch, the capacitor is disconnected from the circuit (with a full charge) when the load pulse is initiated, preventing the capacitor from depleting its energy store by discharging through the load. After the load pulse is terminated by reclosing the main opening switch, the polarity of the counterpulse capacitor voltage is reversed by discharging the capacitor through a small inductor and interrupting the discharge current oscillation at zero current and peak reversed voltage. The circuit enables high-power, high-repetition-rate operation with reusable switches and features total control (pulse-to-pulse) over output pulse initiation, duration, repetition rate, and, to some extent, risetime.

    摘要翻译: 大功率反转对脉冲重复脉冲感应存储和传输电路包括开关开关,主储能线圈,对称脉冲电容器和小电感器。 在反向断开开关后,在启动负载脉冲之前,对准脉冲电容器由主储能线圈再充电。 这样,即使在发生电容器电压的极性必须相反的情况下,对于下一个对位脉冲操作,脉冲电容器就会产生足够的能量。 通过使用电流零开关作为对称脉冲启动开关,当负载脉冲启动时,电容器与电路(充满电)断开,防止电容器通过负载放电而耗尽其能量存储。 在通过重新闭合主开关开关来终止负载脉冲之后,通过小电感器放电电容器并使零电流和峰值反向电压下的放电电流振荡中断,使对称脉冲电容器电压的极性反转。 该电路可实现具有可重复使用的开关的高功率,高重复率操作,并且具有超过输出脉冲启动,持续时间,重复率以及在某种程度上上升时间的总体控制(脉冲到脉冲)。

    摘要: Alternate polarity pulses of current are fed to a load L1A by charging a capacitor C5A alternately in different directions and closing unidirectional switches V2A and V3A at appropriate times to discharge the capacitor C5A through the inductor L1A. This arrangement is considered superior to an alternative system in which different capacitors are charged with different polarities to produce the different pulses. In the latter system the arrangement of switches needs to be such that the closing of one produces transient voltages which might cause the other switch to operate when it is not required to do so. In the illustrated system the switches V2A and V3A, being connected in parallel, do not suffer from this problem. In an alternative system the switches V2A and V3A could be replaced by a single bi-directional switch.

    摘要: An electrical excitation circuit is disclosed for a gas laser. The electrical excitation circuit includes a charging circuit connected in series with a pulse forming network between a power source and the laser load. The charging circuit includes a capacitor charged by the power source and a thyratron for transferring voltage to the pulse forming network. Alternatively, the charging circuit includes a capacitor charged upon the firing of a silicon controlled rectifier through a saturable step-up transformer which saturates for transferring voltage to the pulse forming network. The pulse forming network includes a saturable inductor switch positioned with respect to a capacitor so that when the voltage on the capacitor reaches a predetermined level, saturation of the saturable inductor switch releases electrical energy stored in the capacitor to the laser load.
