This chapter focuses on the control of single-phase and three-phase voltage-source inverters that are widely used for the conversion of AC electrical energy. Pulse-width modulation is discussed as a means of generating reference voltages based on inverter discrete states. Vector representation is introduced for proper analysis of inverter states selection, and carrier-based modulation is considered for simple control implementation. Available degrees of freedom are discussed and classical control methods are presented along with their main limitations and trade-off, exposing the impact of control choices with regard to application constraints.
