“…An MPC strategy was designed to control the current of two-level voltage source inverters in [6] in 2007. From then on, many researchers began to study new MPC strategies to reduce the computational time [7,8], to lower the switching frequency [9,10], to suppress the common-mode voltage [11,12], to decrease the current ripples [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29], or to minimize the power ripples [30][31][32].…”

Recently, model predictive control (MPC) methods have been widely used to achieve the control of two-level voltage source inverters due to their superiorities. However, only one of the eight basic voltage vectors is applied in every control cycle in the conventional MPC system, resulting in large current ripples and distortions. To address this issue, a dual-vector modulated MPC method is presented, where two voltage vectors are selected and utilized to control the voltage source inverter in every control cycle. The duty cycle of each voltage vector is figured out according to the hypothesis that it is inversely proportional to the square root of its corresponding cost function value, which is the first contribution of this paper. The effectiveness of this assumption is verified for the first time by a detailed theoretical analysis shown in this paper based on the geometrical relationship of the voltage vectors, which is another contribution of this paper. Moreover, further theoretical analysis shows that the proposed dual-vector modulated MPC method can also be extended to control other types of inverters, such as three-phase four-switch inverters. Detailed experimental results validate the effectiveness of the presented strategy.

“…This method only operated linearly with low modulation index. The model predictive control (MPC) based CMV reduction strategies were discussed in [17] and [18] to control the output currents with the fast transient response as well as limit the amplitude of CMV. The amplitude of CMV is restricted within 33% of DC-link voltage.…”

This paper introduces a new three-phase two-level inverter based on the switched-capacitor voltage multiplier. By adding a voltage multiplier network at the DC side of the traditional three-phase inverter topology, the DC-link voltage of the introduced inverter is stepped up to triple of the input voltage. Compared to the existing solutions, the common-mode voltage of the introduced topology is kept constant. Moreover, the voltage stress across additional semiconductor components is the same as one-third of DC-link voltage. Operating principles, mathematical analysis, circuit analysis, and pulse-width modulation (PWM) method based on the Boolean logic function for introduced inverter are presented. A comparison of the introduced inverter with other inverter topologies is also reported. The simulation results are shown to verify the introduced three-phase triple voltage boost inverter. Besides that, a laboratory-built prototype is developed based on a DSP F280049C microcontroller and the corresponding experimental tests are provided to prove the introduced inverter. INDEX TERMS Three-phase inverter, transformerless PV system, common-mode voltage, leakage current, switched-capacitor network.
