PWM current source inverter with IGBT transistors and multiscalar model control system

A control system for the induction motor fed by a PWM CSI based on a multiscalar model is presented in the paper. The current source inverter topology and principle of PWM modulation are taken into account. The vector model of the induction motor fed by CSI with output capacitors of inverter is presented in the paper. Complete equations of three multiscalar models of the induction motor are presented. The first multiscalar model is based on the stator current and rotor flux vectors. The second model is based on the stator current and stator flux vectors. The third model is based on the stator current and main flux vectors. Properties of the new control systems are compared and results of simulations are presented.
