Abstract :
In this paper, a three level high voltage VSI (voltage source inverter) adjustable speed IM (induction motor) drive system with IGCTs (integrated gate commutated thyristors) is developed. Two IGCTs are in series connection in each cell of the inverter in order to obtain a 6 kV high voltage output. The DSP (data signal processor) with FPGA (field programming gate array) controller is adopted to fulfill an optimized constant V/Hz control strategy. SHE-PWM (selective harmonic eliminated)-(pulse width modulation) method is carried out to keep sine wave output.
