This paper deals with real-time (RT) simulators applied in power electronic applications and implemented in a real inverter. The process of preparing and starting up an active rectifier prototype (with an active filter function), using the real-time OPAL RT simulator is given. The control system of the converter and the results of simulation using the Matlab/Simulink suite are discussed.
Department of Electrical Drive and Industrial Equipment University of Science and Technology (AGH) The article describes the method of determining mechanical losses and electromagnetic motor torque on the example of a flywheel energy storage system utilizing BLDC motor. The description of the test stand contains: the topology of power factor correction boost rectifier, an inverter supplying the BLDC motor, and the measuring system. The detailed experimental results are included in the paper.
