Abstract: In the research paper we derived the analytical relations describing effective value and total harmonic distortion of line-to-line voltage of multi-phase four-level PWM VSI. The relations allow analyze these converters with general viewpoint and without reference to phase number and PWM methods. The diagrams of reception procedure and graphs of received characteristics are presented.
Keywords: multi-phase four-level voltage source inverter, pwm methods, modulation index, root-mean-square, total harmonic distortion
