Validation of a State Composer Algorithm for a Cascaded Multicell Converter via Real-Time Simulation

The State Composer Algorithm enables a Level-Shifted PWM Modulator to achieve an equal power distribution among the cells of a Cascaded Multicell converter (or similar). This paper reports the implementation and validation of a LS-PWM modulator based on a State Composer Algorithm for a Medium Frequency Railway Traction Converter, supporting up to 10 cells. The results were obtained using a Real Time Simulator.
