By using dual inverter,the actual number of motor phase voltage level is increased. For example, dual two-level inverter operates in three-level mode with equal DC-bus voltages, and operates in four-level mode when the dc voltages are in 2:1 ratio [ 15 ].
6. Extensions Although the proposed dual-vector modulated MPC is aiming to control two-level voltage source inverters, further studies in this paper show that it can also be used to control other types of inverters by only changing the voltage vectors according to the corresponding inverter, which is another important contribution of this paper.
Abstract: 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.
The desired voltage vector of inverter1 will be chosenamong zero vector and basic voltage vectors lying in the feasible region of voltage vector distribution mentioned in Section 2.2, the one makes inverter1’s output power closest to the desired value will be selected. The specific algorithm will be introduced as follow.
Recently, the control methods of two-level voltage source inverters have been widely studied to achieve smooth and flexible energy conversion [1–5]. As is known, vector control is widely used to control two-level voltage source inverters in renewable energy generation systems as it can achieve power decoupling control.
Thus, and can be generated bytwo independent space vector pulse width modulation (SVPWM) controllers. Because the two power sources are electrically isolated, the mid-point voltage difference is floating and varying along with the switching states of dual inverter.
