Common-mode voltage (CMV) in voltage-source inverters (VSIs) has been well defined and is frequently referred to in the literature. While often referred to, there is no real consistency with respect to how the CMV properties of an individual modulati

The nine-switch converter (NSC) has been used in power quality conditioners and AC motor drives. However, it has not attracted much attention because of its amplitude, frequency and phase-shift limitations primarily due to the constraint on the modul

A carrier-based modulation scheme for a three-level diode-clamped five-phase voltage source inverter is presented. This technique employs the generation of three average modulation signals for each inverter leg. These signals are compared with the sa

The advancement in power electronics has made the use of any number of phases in ac machines possible since with the inverter, any number of phase voltages can be realized as long as the corresponding inverter exists. To supply multiphase drives requ

The AC-AC matrix converters are pulse-width modulated using either a carrier-based or space vector modulation techniques. This paper presents these two approaches as they relate to the non-square 5 × 3 converter design targeted for a five-phase volt
