Abstract

In this paper, a 3-phase, Y-connected, 5-level Static Synchronous Compensator (STATCOM) is proposed with reduced number of switches for single phase and unbalanced three-phase loads. The system is implemented and tested under different loading conditions. The level shifted carrier based SPWM method, instantaneous single phase active (P) and reactive (Q) powers are used to control the system. The simulation results obtained from Matlab are compared with the experimental results from the system operated with a DSP TMS320F28335.
