Abstract

Power Semiconductor switches of active rectifier are characterized by highly nonlinear property, resulting in high harmonic distortion and high ripple voltage on the DC side. This paper presents advanced control using switch function and fuzzy logic for compensating nonlinear behaviour. The system applies switch function of time as the input of control strategy, instead of current and voltage in d-q frame. The fuzzy logic controller aims to minimize DC voltage deviation by regulating the line current amplitude. This system uses minimum number of sensors, which is the voltage only to avoid the effect of sensor nonlinearity to the system. This performance is demonstrated and compared with PI-optimized controller. Simulations result have been conducted for variation values of capacitance, inductance and loads. The results show that the harmonic distortion and the ripple voltage on the DC side are 0.036 % compared PI�optimized controller as 5.64 %.
