| Abstract |
The proposed control method for dual converters combines two approaches as space vector PWM (SVPWM) and finite control set model predictive control (FCS-MPC). The SVPWM is used for suitable output voltage vectors preselection and the FCS-MPC enables using a mathematical model of the system and a proposed cost function to reduce power losses and to redistribute power losses among transistors. The suitable switching combination utilizing the redundant switching states is selected according to the preselected space vector. That feature is very advantageous in special operation modes appearing e.g. in electric drives for mining hoists and elevators. |
