This chapter covers the fundamental multilevel converter structures and modulation paradigms. The basic principles of the four main different multilevel converters have been discussed methodically: (1) cascaded H-bridges, (2) diode clamp, (3) flying capacitors, and (4) modular multilevel converter. Various modulation schemes for multilevel converters are also covered including fundamental frequency switching and harmonic elimination and several carrier-based and space vector-based pulse-width modulation (PWM) methods. The chapter also includes significant ...
