This paper proposes a model predictive control-space vector modulation (MPC-SVM) method to achieve current ripple reduction and neutral-point voltage balance in three level inverter. The proposed MPC-SVM method is based on subdivision strategy for improving the performance of the conventional model predictive control (MPC) method. The proposed subdivision strategy consists of two parts: current controller...
Using a Vienna rectifier as the machine-side rectifier of back-to-back converter is advantageous in terms of size and cost compared to three-level topologies and for this reason, the Vienna rectifier has been used in Wind Turbine Systems (WTS). This paper proposes a Model Predictive Control (MPC) method for the Vienna rectifier used in WTS with a Permanent Magnet Synchronous Generator (PMSG). The...
This paper presents a control scheme for the dynamic performance improvement of an AC/DC converter using the model predictive direct power control (MPDPC) with a duty cycle. In the MPDPC, the active and reactive power is simultaneously controlled with a single cost function. If either of the two control targets has a large power variation, the control weight is concentrated on one side, which causes...
This paper proposes an improved model predictive control (MPC) algorithm for the direct torque and flux control of induction motors (IMs) using the three- level inverter. To reduce the calculation amount, which is the drawback of MPC, first the reference value and the state of the motor are analyzed to preselect the calculation region for the cost function; by only subdividing the voltage vectors...
