A Straightforward Deadbeat Control Scheme for Three-phase Voltage Source Inverters

Conventional finite control set model predictive control (FCS-MPC) methods are well-known for their variable switching frequency, leading to noise and significant voltage and current ripple. Based on model predictive control, this study introduces a straightforward deadbeat control method with a constant switching frequency for a voltage source inverter, in order to provide a modulated waveform at the output of the converter. The proposed method achieves fast dynamic response since the load current tracks the reference current after two sampling intervals. The practicality of this technique is assessed through simulation results that emphasize the positive attributes of the proposed method.
