   HIGH POWER WATER COOLED THREE-LEVEL GTO-MODULES FOR THE STATIC FREQUENCY CONVERTER MULDENSTEIN
By P. G. Kamp [View]
[Download]

Abstract: Water cooled three-level power modules with 4 kA-GTOs for application in voltage source static frequency converters have been developed. These modules, their internal circuitry, cooling system and their electrical arrangement for the static frequency converter Muldenstein are described. Attention· is given to the choise of the GTO-thyristor and the realisation of the snubber circuits respecting the three-level technique. Results of measurements on GTO modules and on a three-phase converter are presented in this paper.

   CURRENT CONTROL METHOD FOR A NOVEL SINGLE-PHASE SINUSOIDAL PWM VOLTAGE SOURCE INVERTER
By S. Nonaka [View]
[Download]

Abstract: A novel single-phase composite PWM voltage source inverter (VSI) is proposed. The VSI provides a sine wave output current and high power factor. The current control method of the inverter is described when it is applied to a utility-interactive residential photovoltaic system, for example.

   CURRENT RIPPLE ANALYSIS OF HYSTERESIS-CONTROLLED INVERTERS INTRODUCING CONCEPT OF CONDUCTION PROBABILITY
By T. Kataoka; P. A. Dahono; Y. Sato [View]
[Download]

Abstract: A novel method for analysis of input current ripple is presented which is suitable for hysteresis-controlled inverters in which the switching pattern for switching devices can not be predetermined. This method introduces a concept of conduction probability for the switching devices. The results of analysis are confirmed by experimental investigation.

   HIGH CURRENT LOW VOLTAGE POWER SUPPLIES WITH HIGH POWER FACTOR, LOW HARMONICS AND LOW COSTS
By D. Pratmarty; N. Buchheit; H. Pouliquen; O. Apeldoorn [View]
[Download]

Abstract: High current low voltage power supplies are used in several production processes, particularly in heating technology. Various structures in the range of 100 kW to a few MW are studied. The main objectives are to limit harmonic pollution and to improve the input power factor of the power supply. A comparative evaluation of its low frequency Electro Magnetic Compatibility (EMC), speed of control and the ratings of power electronic components enables an estimation of the best topology for a given application.
