【Abstract】 One-cycle control is a novel nonlinear control method.Its basic control concept is to force the mean switching variables to be equal or proportional to the control references,so as to eliminate the stable and transient errores.This peper introduces the operating principle,control method and features of single-phase,three-phase three-wire and three-phase four-wire active power filter (APF) using one-cycle control.The one-cycle controlled APF needs no amplifier and voltage sensor,so its testing ciruit for harmonic and current travring control circuit are simplified greatly,and it has the merits of simple structure, high precision and quick responce.更多还原
