A model based predictive direct power control with finite set of control variables for the three phase four-switch-based converter B4 connected to an unbalanced grid is introduced. The instantaneous active and non-active powers are outputs of the controlled system. The alternative instantaneous non-active power theory is used that preserves harmonic free grid currents not only for a symmetrical but also unsymmetrical voltage system. Simulation results for the L grid filter are presented and analyzed
