Model RT (czasu rzeczywistego) trójgałęziowego falownika napięcia

The article presents the idea of digital three-phase model of 3-branches voltage inverter, functioning in real time. The use of programmable logic systems research aims to allows you to test the inverter control algorithms in the same control device through the parallel work with real time model of inverter. Logical layout used in the research was the FPGA type produced by Altera of EP3C40. Inverter model is not only used in a sequential way, but also parallel determination of the answers of selected logical blocks. Developed inverter model has been tested using the tools available in the Quartus II software. Recorded inverter voltages for two methods of modulation are presented in the article as part of the verification of the correct operation of the model.. Dynamic state is observed for a various types of models of the transition state. Inverter model made quick verification of the control algorithm for the correctness of the operations without having to perform laboratory tests, which can end with costly repairs.
