| Abstract | Harmonic voltages and currents in an electric power system are a result of non-linear electric loads. Usually a STATCOM is installed to support electricity networks that have a poor power quality. In this work, a multilevel Active neutral point converter with separated dc capacitors which is driven by carrier-based pulse width modulation to implement in the STATCOM is proposed. Active NPC (ANPC) improves the loss distribution of NPC by replacing diodes with active switches providing alternative neutral point path. A PID controller is designed to obtain the desired level of the output. This application is designed in the MATLAB/ Simulink platform. With the phase-shifted carrier based scheme, natural balancing can be achieved in a straight forward manner. However, to achieve natural balancing with the optimum harmonics, phase-disposition (PD) carrier-based scheme which use the (n − 1) carrier signals is proposed. The relationship between the average neutral-point current and zero sequence voltage is investigated, and an optimum zero-sequence voltage is calculated to regulate the neutral-point potential. |
