This paper proposes a model predictive current control (MPCC) method for a three-leg two-phase voltage source inverter to reduce the ripple of the 

output current. The proposed MPCC method is based on discrete space vector modulation, which is implemented by eliminating nonlinear modulation regions and generating virtual voltage vectors based on the stationary reference voltage vector axis. In addition, based on the voltage angle estimated using load parameters, the candidate voltage vectors in a specific region are generated, which reduces the calculation burden. Subsequently, the 

cost function is calculated using these candidate voltage vectors, and the optimal voltage vector selected using the proposed MPCC method is more 

accurate than that selected using the conventional MPCC method. Therefore, by applying the proposed method to increase the number of virtual 

voltage vectors, we obtain a delicate reference voltage. Consequently, the total harmonic distortion of the output current is reduced, resulting in an 

increase in power quality. The effectiveness and feasibility of the proposed method were verified through simulations and experiments.
