In this paper a new method four-leg topology is suggested for shunt compensation, the H-bridge multilevelconverters based on the half-bridge converters, to achieve higher performance as a STATCOM in a distortedand unbalanced medium-voltage large-current system. Further, an extended Fuzzy based STATCOM isproposed in order to manage more accurate compensation for high-power applications. Both proposals can becontrolled for various purposes such as reactive power and unbalance compensation, voltage regulation, andharmonic cancellation. One interesting application for the Fuzzy logic based STATCOM could be theimprovement in power quality and performance of the electrified railway traction power supply system. Boththe H-bridge based STATCOM along with their proposed control strategies were simulated.
