Predictive power control (PPC) is emerging as a powerful alternative to conventional direct power control (DPC) due to its more accurate vector selection and flexibility in considering various constraints. However, similar to conventional DPC, applying only one voltage vector during one control period still presents relatively high power ripples and broad harmonic spectrum in PPC. To obtain satisfactory performance with PPC, very high sampling frequency is necessary, which increases the hardware burden. This paper proposes an proposed PPC by dividing the control period into two intervals, one for the active vector and another for a zero vector. The principle of deadbeat control of active power is introduced to determine the duration of the active vector. Experimental results prove that better steady performance is obtained in the proposed method while the dynamic response not affected.
