Abstract

This paper dwells upon a rectifier drive based on a permanent magnet synchronous motor (PMSM). An additional boost regulator connected to the DC link helps maintain an increased voltage at the self-commutated voltage inverter (SCVI). A double-loop vector control system controls the drive and uses a joint relay control algorithm to control the boost regulator and power IGBT-transistors in the SCVI. The boost regulator is controlled using the input-output power balance equation. This system ensures a sinusoidal current waveform at the inverter output. The electric drive has been modeled in Matlab Simulink to study its properties. It is also possible to analyze the current harmonics to evaluate the designed drive for electromagnetic compatibility with the power grid.
