  • Estimation of EMI Filter Performance for the \"Worst Case\" System 

    Drinovsky, J.; Svacina, J. (Společnost pro radioelektronické inženýrství, 2006-12)
    This paper deals with the performance problem of the EMC filters. The core of this problem in EMC filter is the uncertainty of impedances that are connected to the input and output of a filter. In addition, an estimation ...
  • Estimation of the EMI Filter Circuitry from the Insertion Loss Characteristics 

    Kejik, Z.; Drinovsky, J.; Ruzek, V. (Společnost pro radioelektronické inženýrství, 2010-06)
    The paper deals with the EMI filter models for the calculation of the insertion loss characteristics. The insertion loss is in fact the basic EMI filter property. Unfortunately it is not easy to precisely define and measure ...
  • Evolutionary Synthesis of Fractional Capacitor Using Simulated Annealing Method 

    Slezak, J.; Gotthans, T.; Drinovsky, J. (Společnost pro radioelektronické inženýrství, 2012-12)
    Synthesis of fractional capacitor using classical analog circuit synthesis method was described in [6]. The work presented in this paper is focused on synthesis of the same problem by means of evolutionary method simulated ...
  • Feature Selective Validation of Automotive EMC Pre-compliance Tests 

    Ruzek, V.; Drinovsky, J.; Cupak, J. (Společnost pro radioelektronické inženýrství, 2018-04)
    The pre-compliance tests of electromagnetic immunity are at present a crucial issue for all major automotive manufacturers. In current practice, there are two basic ways to implement these tests. The first one is based on ...
  • Insertion Loss Estimation of EMI Filters in Unmatched Input/Output Impedance System 

    Drinovsky, J.; Kejik, Z.; Ruzek, V.; Zachar, J.; Svacina, J. (Společnost pro radioelektronické inženýrství, 2011-04)
    One of the problems in the design of powerline EMI filters is the uncertainty and ambiguity of their source/load impedances which results in breach of expected filter parameters in a real installation. The paper presents ...
  • Multi-Objective Self-Organizing Migrating Algorithm: Sensitivity on Controlling Parameters 

    Kadlec, P.; Raida, Zbyněk; Drinovsky, J. (Společnost pro radioelektronické inženýrství, 2013-04)
    In this paper, we investigate the sensitivity of a novel Multi-Objective Self-Organizing Migrating Algorithm (MOSOMA) on setting its control parameters. Usually, efficiency and accuracy of searching for a solution depends ...
  • Potential Worst-case System for Testing EMI Filters Tested on Simple Filter Models 

    Drinovsky, J.; Svacina, J.; Raida, Zbyněk (Společnost pro radioelektronické inženýrství, 2008-09)
    This paper deals with the approximate worst-case test method for testing the insertion loss of the EMI filters. The systems with 0.1 Ω and 100 Ω impedances are usually used for this testing. These systems are required by ...
  • Simple Models of EMI Filters for Low Frequency Range 

    Drinovsky, J.; Svacina, J.; Raida, Zbyněk (Společnost pro radioelektronické inženýrství, 2008-09)
    This paper deals with mathematical simulations of EMI filters’ performance. These filters are commonly used for the suppressing of electromagnetic interference which penetrates through the power supply networks. The ...
