Abstract

An analysis and experimental verification of the operating point stability of the line-start permanent synchronous machine (LSPMSM) supplied from a current source provided with power factor control is presented. The control system acts to inject the stator currents at a controlled angle related to the stator voltages. The machine parameters are varying because of magnetic saturation and as a result the control performances are affected by saturation. The effects of magnetic saturation and inverter imperfections are included.
