Abstract
Four quadrant modulation techniques that can synthesize a full range solution or a full modulation index range are provided. Such techniques can be applied to a DC/AC inverter, an AC to DC rectifier, and AC/DC/AC topology. The techniques can also be applied to a neutral point clamped (NPC) topology, flying capacitor (FLC) topology, cascaded H-bridge (CHB) topology, modular multilevel topology, modular multilevel converters, and multimodule converters.
