| Abstract: | This paper presents a three-level three-phase three-wire active power filter. A nonlinear control method, one-cycle control, is used to control the active power filter. It has simplified circuit and high precision and effectual compensation. In addition, it employs constant switching frequency modulation that is desirable for industrial applications. Simulation is carried out on the basis of a mathematic model. The simulation results verify that the three level APF with one-cycle control can dynamically and effectually compensate the harmonics. |
