Abstract
Model Predictive Control (MPC) can provide performance benefits over established schemes in power electronic converter control. However, the implementation of the scheme changes the characteristics of the voltage and current control systems relative to established control methods and different approaches for control are required. This paper considers the implication of the speed of the stack voltage balancing scheme on the regulation of the capacitor voltages in a 5 level cascaded h-bridge StatCom. A dead-beat scheme with phase shifted carrier pulse width modulation (PSC-PWM) and a finite control set model predictive control (FCS-MPC) scheme are compared with simulation results.
