Abstract

A method for reducing the signal harmonics of the output fundamental signals of a three-phase inverter systems made up of an N number of inverter bridges achieves harmonic signal reduction by combining the outputs of immediately adjacent bridges separated by 60°/N relative to one another and then summing the combined sum signal with the outputs of the next immediately adjacent bridge.
