   Reduction of Conducted Line Emissions in Voltage-Fed Pulsed Inverters by using Suppressor Capacitors in the Intermediate Circuit
By H. Joergensen; S. Guttowski; K. Heumann [View]
[Download]

Abstract: This paper presents fundamental considerations on the possibilities and limits of noise reduction in pulsed inverters by grounding the intermediate circuit for high frequencies. Our main focus is the connection between noise reduction and the caused leakage current. These considerations are preceded by an attempt for a theoretical description of emission paths in pulsed inverters.

   PREDICTIVE CORRECTION METHOD FOR FAST CONTROL SYSTEMS WITH RESPECT TO THE EXAMPLE OF STATIC V AR COMPENSATION OF ARC FURNACES
By Th. N. Le; G. Vaupel [View]
[Download]

Abstract: A predictive correction method for fast control systems with respect to the example of static V AR compensation of arc furnaces is presented. Applications with fast control methods have limited accuracy due to disturbances such as harmonics in control signal. This paper describes a method of correcting the control signal, which is based on actual control errors and their time derivatives. In case of static V AR compensation of arc furnaces with the flicker reduction as main aim, it is shown that results are improved significantly by employing the proposed method.

   ELECTROMAGNETIC RADIATION FROM POWER ELECTRONICS CIRCUITS
By M.Youssef; J.Roudet; Y.Marechal [View]
[Download]

Abstract: In this paper, theoretical analyses and experimental results are carried out on the radiated emission from a power converter circuit. A software program (InCa) is used to study the distribution of the current along the circuit's wires. Calculations of the radiation are introduced on the basis of antenna theory, and are in excellent agreement with the experiment.

   STANDARDISATION IN POWER ELECTRONICS
By J.-L. Sanhet [View]
[Download]

Abstract: Innovation in the field of power electronics has been significant in recent years. Industrial power electronic developments followed those innovations to propose new products, new performances, new services to the general industry. Standardisation is the necessary way to help in enlarging the use of power electronics. Standardisation of power electronics, normally performed in IEC-TC22, can be helped by the new technical committee 22X of CENELEC in charge of the european questions.
