  • Effects of power-train parasitic capacitance on the dynamic performance of dc-to-dc converters operating in the discontinuous mmf mode

    Publication Year: 1985, Page(s):3 - 19
    Cited by:  Papers (5)
    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (7794 KB)

    This paper investigates a widely observed phenomenon where a dc-to-dc converter operating in the discontinuous mmf mode with a constant-frequency control law can exhibit wide variations in dynamic performance over a narrow range of input voltage or output load. This behavior is related to the sinusoidal energy exchange between the parasitic capacitances of the power stage and the energy-storage re... View full abstract»

  • Efficient snubbers for voltage-source GTO inverters

    Publication Year: 1985, Page(s):20 - 27
    Cited by:  Papers (1)
    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (4535 KB)

    The two gate turn-off thyristors in the phase leg of a voltage-source inverter are provided with a series center-tapped inductance snubber and shunt capacitor snubbers having a single discharge resistor and only two auxiliary diodes. This arrangement minimizes the number of components and allows reduction of capacitor size, thereby reducing the snubber losses. The resistor may be replaced by a tra... View full abstract»

  • Dead beat microprocessor control of PWM inverter for sinusoidal output waveform synthesis

    Publication Year: 1985, Page(s):28 - 36
    Cited by:  Papers (10)
    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (6073 KB)

    A new control technique based on dead beat control theory to obtain a nearly sinusoidal PWM inverter output voltage is described. The closed loop digital feedback system measures the output and controls the inverter switches to generate the required PWM pattern to produce low total harmonic distortion (THD) sinusoidal output voltage. This scheme inherently provides very good voltage regulation, ph... View full abstract»

    The 500V junction-isolated BiMOS high voltage IC process technology recently introduced by the General Electric Company(1,2) and now in manufacturing production provides the circuit designer with a myriad of low and high voltage devices. However, to exploit the full capability of this process and apply it efficienty, it is crucial to understand and model the devices it makes available. This paper ... View full abstract»

    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (1422 KB)

    In the control of adjustable speed drives, the performance of inexpensive digital integrated circuits is approaching the stage where traditional control algorithms may be displaced by newer algorithms that better exploit their speed and the functional capabilities of their software. This paper introduces the concept of “instantaneous torque control” as an objective worth pursuing in the applicatio... View full abstract»

  • SEMINET: Power Circuit Analysis Including Numerical Semiconductor Device Models

    Publication Year: 1985, Page(s):49 - 55
    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (1445 KB)

    This paper describes a recently developed computer program called SEMINET (for SEMIconductor NET-work). SEMINET enables user-oriented modeling of electronic circuits including “exact” numerical analysis of power semiconductor circuit elements. Analytical semiconductor device models are also available in addition to the usual complement of passive components and voltage and current sources. General... View full abstract»

  • State-plane analysis of parallel resonant converter

    Publication Year: 1985, Page(s):56 - 73
    Cited by:  Papers (91)
    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (4223 KB)

    A method for analyzing the complex operation of a parallel resonant converter is developed, utilizing graphical state-plane techniques. The comprehensive mode analysis uncovers, for the first time, the presence of other complex modes besides the continuous conduction mode and the the discontinuous conduction mode and determines their theoretical boundaries. Based on the insight gained from the ana... View full abstract»

  • Optimal pole assignment for power electronic systems

    Publication Year: 1985, Page(s):74 - 88
    Cited by:  Papers (7)
    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (1993 KB)

    An optimal pole assignment concept for a closed loop feedback control is proposed and its advantages are discussed. Precise tracking of a reference signal and disturbance rejection with quick transient response can be achieved with this theory. The importance of loss of observability by pole-zero cancellation is stressed. Examples of the control of a PWM inverter and superconducting magnet are dem... View full abstract»

  • The application of power MOSFETs at 10MHz

    Publication Year: 1985, Page(s):91 - 100
    Cited by:  Papers (10)
    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (5038 KB)

    The design and performance of a 10MHz dc/dc converter is discussed. The behavior of the power MOSFET at this frequency, and the integration of device parasitics into the circuit are described. The performance of a 50W converter is compared with the predictions of a detailed simulation. Losses are analysed and shown to be dominated by MOSFET switching. View full abstract»

    Publication Year: 1985, Page(s):101 - 105
    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (1105 KB)

    A novel system including many solar cells and a secondary battery is presented. These energy sources are connected to each other with a bus bar through inverters and supply ac power to loads on the bus bar. The output voltage of the solar cell is always kept constant in order to derive the almost maximum output power from the solar cell when the light strength from the sun is varied. When multiple...

    In designing conventional switching converters, the effort to increase operating frequency in order to reduce weight, size and cost of magnetic and filter elements is constantly hampered by higher switching stresses and switching losses. To overcome these obstacles, the concept of resonant switch was proposed. By incorporating additional Land C elements to shape device current and voltage waveform... View full abstract»
