Abstract :
This paper discusses three kinds of triangle carrier PWM strategies (subharmonic PWM, triangular carrier phase shifting PWM, and switch frequency optimal PWM) applied to a cascade multilevel converter (cascade inverters with separated DC sources). The control effects of them are compared through simulation results using Saber simulation software. Some conclusions and suggestion are given
