Simulation of The Electrical Phase Converter Connecting a Three-Phase Motor to A Single-Phase Network

摘要

The article considers a simulation model of the operation of a semiconductor converter. It allows to connect a three-phase induction motor to a single-phase electrical network and provide a three-phase symmetrical voltage on the stator winding. The parameters of elements included in the structure of the phase number converter are calculated. Authors have designed a simulation model using The Simulink Matlab software which describing the operation of the phase converter and confirming the theoretical conclusions. Calculation expressions are given for determining the parameters of the smoothing filter, which is included in the structure of the phase converter. The harmonic spectrum of the phase voltage at the output of the converter is analyzed.
