Vector Modulation

In this paper, the hysteresis current control (HCC) technique based on space vector modulation (SVM) for active power filter (APF) is proposed. The switching control algorithms of the HCC based SVM manage to generate compensated current according to the reference current. Harmonics extraction is calculated for the power compensation based on the instantaneous active and reactive power theorem in time domain. A closed loop control system is carried out and the APF manages to generate better compensated harmonics currents to the power grid.

Taking three-level four-leg active power filter (APF) as research object, this paper establishes the corresponding mathematical model. In addition, the paper establishes the Matlab model based on predictive current control strategy, and then the theoretical analysis and simulation research are conducted. The simulation and experimental results show that the APF with predictive current control strategy can compensate harmonic current and neutral current well and make the two capacitors voltage balance effectively.

This paper presents a new hysteresis current control method for APF(active power filter) that can reduce switching losses effectively by means of adjusting the hysteresis band width according to the current size. On one hand, this method adjust the overall hysteresis band width according to the size of absolute norm of three-phase current that optimize the overall switching frequency, reduce the total switching losses effectively. On the other hand, it adjust hysteresis band width of each phase by comparing the output reference current to reduce the switching times which switching losses is larger, while increasing the switching frequency which switching losses is smaller, so as to maintain overall control precision. Computer simulation is conducted on an electromagnetic transient program. The results show that the new method can effectively reduce the switching losses under the same control accuracy and total switching frequency.
