To address major concerns about the grid connected phase-controlled rectifiers, such as highly distorted grid currents, a poor input power factor, and a very slow dynamic performance, the voltage source PWM rectifiers have attracted great attentions today. As an advanced control strategy, the voltage-oriented control (VOC), is widely used to control the grid connected converters. The VOC uses the concept of decoupled active and reactive current components in the synchronous reference frame (SRF). Though, the VOC has been well documented in its theoretical aspects, but the absence of systematic design guidelines, that also cover the practical aspects such as analog anti-aliasing filtering and digital implementation delays, is obvious. Based on the symmetrical optimum (SO), and its extended version (ESO), this paper presents step-by-step guidelines for designing the near-optimum ac current and dc voltage controllers of the VOC controlled grid connected rectifiers, with considering all practical aspects. Also, the effect of controllers’ parameters on the performance of the converter is explained. Extensive simulation and experimental results are provided which confirm the validity of the proposed technique.
