Abstract :
This paper presents hysteresis current regulation techniques of four-wire loads under balanced and unbalanced conditions, using a three-phase inverter with a neutral leg. It has been shown that well known techniques of hysteresis current regulation used in conventional three-phase three-leg inverters, (three independent hysteresis, three-level hysteresis, and multi-level hysteresis) can also be applied in four-leg inverters
