High power modulators contain various stages of power conversion, from low voltage AC to high voltage DC, which usually receive their input power from public utility mains. These mains are subject to transients (over voltage surges and under voltage dips) that may last from several microseconds, to several hundred milliseconds or to a total blackout of power. The power modulator must operate without failure during the transient line conditions, the full l o s s of AC power, and the restoration of AC power.

Introduction Life time tests are being performed on high power, Size E ignitrons for possible use in the Nova upgrade facility with is currently designed by Sandia and Livermore National Laboratories. The testing is done up to the 300 kA level with a charge transfer of 200 C. The bank used in the experiments is a large electrolytic bank containing over 4000 electrolytic capacitors. The maximum charging voltage of the bank is limited to 4000V; giving 1000 volts margin to the absolute maximum bank voltage of 5000V. Two ignitrons are connected in series to enable High-Pot testing of the tubes after recovery with a low power, H V supply without the need to disconnect any high current connections. Tests were performed on a NL-9000A and a NL-1057 tube, both made by Richardson Electronics. The current as well as the differential voltage drops across both tubes were recorded along with the charging voltage and the differential voltage drops at peak current (dI/dt=O). The forward voltage drop of the NL-1057 was about twice as high than the voltage drop across the NL-9OOOA. Detailed waveforms and data evaluations are shown. The ignitor resistance, which is a barometer for the life expectancy of a tube, was also recorded frequently. In addition, new PSpice circuit models for the ignitrons and the test stand were developed using many of the advanced features of PSpice 6.0 for Windows. Many pulsed power applications that use capacitor banks for energy storage need a reliable closing switch to release the energy into the load. Up to the present day, those switches are a focus of many developments and concerns. In the latter part of the 80's and the beginning of the ~ O ' S , ignitrons have been redesigned for high peak current, high charge transfer capability1 >2, The new high power Ignitrons like the NL_9000A, made by Richardson Electronics, and the BK-1002, made by EEV, have inverted, cup-style anodes with drastically reduced Anode-Cathode spacing as well as center ignitors. The test program reported here was conducted in order to evaluate the performance and lifetime of these ignitrons for pulsed power applications.

Photoconductive semiconductor switches (PCSS) have high voltage hold-off and fast rise times. When operated in the nonlinear mode the requirement for optical trigger energy is reduced. A two dimensional time dependent computer model has been developed to investigate laser triggering and gain of GaAs PCSS. The role of transport of band-to-band recombination radiation in switch operation is discussed. The location of the laser spot which activates the switch is also investigated.

This paper describes the electrical design and operation of a high power modulator system implemented for the Los Alamos Plasma Source Ion Implantation (PSII) facility. To test the viability of the PSII process for various automotive components, the modulator must accept wide variations of load impedance. Components have varying area and composition which must be processed with different plasmas. Additionally, the load impedance may change by large factors during the typical 20 uS pulse, due to plasma displacement currents and sheath growth. As a preliminary design to test the system viability for automotive component implantation, suitable for a manufacturing environment, circuit topology must be able to directly scale to high power versions, for increased component through-put. We have chosen an evolutionary design approach with component families of characterized performance, which should Ion result in a reliable modulator system with component lifetimes. The modulator utilizes a pair of Litton L-3408 hollow beam amplifier tubes as switching elements in a ``hot-deck`` configuration. Internal to the main of planar triode hot deck, an additional pair decks, configured in a totem pole circuit, provide input drive to the L-3408 mod-anodes. The modulator can output over 2 amps average current (at 100 kV) with 1more » kW of modanode drive. Diagnostic electronics monitor the load and stops pulses for 100 mS when a load arcs occur. This paper, in addition to providing detailed engineering design information, will provide operational characteristics and reliability data that direct the design to the higher power, mass production line capable modulators.« less
