مستخلص: 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.
