    An analysis is presented for the transfer functions of a particular pulse-width modulator and power switch subsystem that has been widely used in practical switching-mode d-c regulator systems. The switch and filter are in a "buck" configuration, and the switch is driven by a constant- frequency variable duty-ratio push-pull magnetic modulator employing square-loop cores. The two transfer function... View full abstract»

    One of the earliest-developed and still widely-used dc to square-wave inverters is the Royeror Uchrin-Taylor configuration shown in Fig. 1. Although the circuit is composed of very few components, its proper operation depends on complex interactions of the transformer as it switches between its unsaturated and saturated regions, and the tow transistors as they switch between cut-off and saturation...

    The transient and steady state performance of a group-triggered cycloconverter supplying a controlled slip induction motor is studied using an analog computer. System equations are derived from equivalent circuits for the cycloconverter, source, and motor networks. The induction motor is represented in terms of qdo components in a stationary reference frame. Computer results are compared with test... View full abstract»

    A new modulation technique has advanced the state of the art in pulsed high power short arc xenon flashlamps. The design of a 50 kW pulsed average power xenon arc lamp was predicated on the development of a push-pull type of modulator to enable heat to be equally extracted from both electrodes. Normally, arc lamps are pulsed from a dc source resulting in high anode temperatures and consequent dete... View full abstract»

    USAMERDCs development efforts have been directed toward compact and efficient power supplies in order to cut the weight and bulk of power conditioning equipment presently used. In this effort, weight reduction has been achieved at the cost of considerable equipment complexity and possible difficulties concerning field serviceability by semi-skilled personnel. This complexity is mainly due to the r... View full abstract»

  • Soft commutation of high power SCR inverters

    Publication Year: 1972, Page(s):103 - 105
    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (360 KB)

    In the process of developing a high power inverter utilizing S.C.R.'s in high voltage D.C. bridges, it became apparent that the commutator circuit would determine the inverter size and weight. Therefore, we developed a single co mutator circuit that was capable of commutating multiple bridges. Using similar reasoning we felt that the commutator should be as conservative of power as possible. These... View full abstract»

    The self-healing fuse is a very fast acting current overload protective device which opens and recloses in a few milliseconds. The fuse confines a mercury column in an insulated channel and returns the mercury to the channel after firing. Ratings 5 to 50 amperes at 600 peak volts are possible with a life of hundreds of cycles. Compared to conventional fuses, much less fault current energy fires th... View full abstract»
