    The modern switching converter/regulator is the major tool of the power conversion specialist and certainly symbolizes the power electronics field. Each of the papers to be presented in this first session deals with switching regulators in some fashion. The hardware world of switching regulators/converters is somewhat artificially partitioned into the transistor based regulators and converters and... View full abstract»

  • General theory of switching power converters

    Publication Year: 1979, Page(s):3 - 10
    Cited by:  Papers (16)
    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (1256 KB)

    A unified general theory of the operation and performace of switching power converters is presented. It differs from prior approaches in that it addresses converters according to func­ tion rather than topology, and in the way conver­ ter analyses are approached. Relationships be­ tween converters are clarified, the inherent un­ desirable aspects of switching converters are seg­ regated from those... View full abstract»

  • 20 kW inverter flyback charging system

    Publication Year: 1979, Page(s):25 - 31
    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (6922 KB)

    A 20 kW inverter flyback charging system has been developed and produced for the ARSR-3 air route surveillance radar system. This precision regulated charging system is used in the transmitter to charge the PFN in a 14- megawatt peak power modulator to over 3,000 volts. The technique used completely eliminates the need for the con­ ventional regulated, high voltage power supply and the dissipative... View full abstract»

  • Computer analysis of thyristor chopper circuits with detailed device modeling

    Publication Year: 1979, Page(s):32 - 39
    Cited by:  Papers (1)
    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (916 KB)

    A computationally efficient computer large signal simulation of thyristor chopper circuits is presented. Nonlinear circuit models are used to represent the active circuit components in a Gear iteration algorithim. The forced steady-state response of the system is found by linear­izing the system at each time step and evaluating the equivalent state transition matrix. In addition, the steady-state ...

  • Start-up transient of a DC-to-DC converter powered by a current-limited source

    Publication Year: 1979, Page(s):40 - 52
    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (1761 KB)

    An analysis technique is presented which permits the designer to explore the start-up transient of a dc-to-dc converter when it is powered by a current-limited source. The current versus voltage characteristics of the source are superimposed upon those of the dc-to-dc converter. By noting the nature of the intersectition of these curves in the voltage-current plane, we are able to predict whether ... View full abstract»

    A power Darlington transistor Subscrete<sup>R**</sup> and hybrid integrated circuit consisting of two of these in parallel with a fast recovery diode are described. The integrated unit is used as a dc-to-dc converter or "chopper" to control the acceleration and speed of a electric car motor and can deliver 450A of armature current. The Subscrete form permits full testing and matching o... View full abstract»

  • Selection of snubbers and clamps to optimize the design of transistor switching converters

    Publication Year: 1979, Page(s):62 - 74
    Cited by:  Papers (3)
    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (1854 KB)

    In power transistor switching circuits, shunt snubbers (dv/dt limiting capacitors) are often used to reduce the turn-off switching loss or prevent reverse-biased second breakdown. Similarly, series snubbers (di/dt limiting inductors) are used to reduce the turn-on switching loss or prevent forward- biased second breakdown. In both cases, energy is stored in the reactive element of the snubber and ... View full abstract»

    To minimize the switching loss of high frequency thyristors, three kinds of multifinger gates and emitter designs are studied. The device characteristics were evaluated. The power loss during high frequency operation was measured. The rate of rise of forward current was studied. View full abstract»

  • A switching amplifier for capacitive loads using incremental resonant charging

    Publication Year: 1979, Page(s):98 - 108
    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (1521 KB)

    A lightweight, compact, 61-channel linear switching amplifier system has been developed for aircraft use. Each channel accepts input in the +10V range and outputs +1500V. into a capacitive load of 0.05 μf. The design employs a system of predictive incremental resonant charging (PIRC) of the load, controlled by a system clock. Central to the concept of PIRC is a means of calculating switching time ...

    Investigation of a wide variety of switching converter toplogies culminates in the establishment of the most general correlation between the converter topologies--the duality relationships. The recognition of this general law leads to a number of new results: new converter topologies generated by the application of the duality transformation to the existing converter configurations, the discovery ...
