AbstractThis paper presents a systematic procedure to design a simple control for a three-phase VSC-based static synchronous compensator (STATCOM) in order to overcome the problems caused by the presence of the non-linear load at the point of common coupling (PCC). The proposed control method regulates the STATCOM in such a way that the source quadrature current component is forced to be zero so that only the active current component is drawn from the source and the harmonic and reactive current demands of the non-linear load are met by the STATCOM. The tuning of the inner and outer loop PI controllers is carried out with the help of the modulus optimum and symmetric optimum criteria, respectively. At last, a few case studies are presented using MATLAB simulation to exemplify the success of the proposed control method.

This paper explores the level of conducted EMI in a buck boost converter under a non linear load condition based on the CISPR 11 / Class A EMC standard. Here, the buck boost converter was designed to produce a constant output voltage irrespective of load conditions. The closed loop control is designed using dsPIC controller. Three different randomization firing schemes are adopted and the EMI analysis in each mode is done experimentally. Also, the results are compared with normal PWM scheme. The experimental result shows that in RPWM scheme the emission levels are comparatively low.
