초록

The conventional current and voltage control methods of AC/DC power factor correction (PFC) rectifiers have been applied using proportional-integral (PI) or proportional-resonant controls. However, these approaches do not guarantee global stability at various operating points and are sensitive to disturbances, such as parameter or load variations. In this paper, a new control method is proposed based on the Lyapunov function that provides global stability and a fast response at various operating points. Experiments are conducted using an air conditioner with a 3 kW capacity. Experimental results are obtained and thoroughly analyzed.
