Abstract

Dual-output four-leg inverter topology can feed two three-phase four-wire loads simultaneously, providing a path for neutral current of both loads. In this paper, a switching technique is proposed for dual-output four-leg converter based on the space vector modulation (SVM) technique. When a proper arrangement of the voltage vectors is used, SVM can achieve different goals, as opposed to carrier-based modulation, where there is no flexibility in choosing the switching pattern. In the proposed SVM technique, the proper arrangement of the voltage vectors is given such that minimum THD and switching losses are achieved. To validate the proposed approach, a dual-output four-leg inverter has been implemented using the given switching technique. The experimental results validate the mathematical analyses and verify the performance of the proposed approach.
