American Modelica Conference 2020 Electromechanical Systems Object Oriented Modeling and Control Design for Power Electronics Half-Bridge Converter using Modelica With the enhancements of power semiconductors the application of power electronics has been extended from traditional domestic and industrial applications to electric power systems. The power-electronic converters for power systems are used especially for power compensation and power filtering. Such converters consist of a power circuit realized through different configurations of switches and passive components coupled with a control system. In this paper the focus will be on a particular type of converters that is the two-level VSC (DC/AC Voltage Source Converter). In this category the averaged model and the switching model of an half-bridge converter will be considered. The half-bridge is a building block for multiphase and multilevel converters. The implementation of the two models of half-bridge converter using Modelica language will be described with the structure of the package developed in Dymola. Different control strategies will be introduced showing different behavior of the models in the simulations.
