Abstract :
Carrier phase-shifted SPWM (CPS-SPWM) technique is applied to current-source multi-modular converter with output current harmonics minimization and without the use of high frequency modulation. A mathematical model of multi-modular CPS-SPWM technique is built and analyzed. Then a digital current-source CPS-SPWM signal generating technique is developed. The proposition is verified by the experimental waveforms and the simulation results.
