Abstract

This paper proposes an independent drive system of two permanent magnet synchronous motors (PMSMs) fed by a four-leg inverter (4LI) with vector control method. The 4LI consists of four legs and two capacitors connected in a series. This paper shows an expanded two-arm modulation to obtain balanced three-phase AC voltage. Also, this paper proposes the compensation method for voltage of two-split capacitors. Next, the independent speed drive of two PMSMs fed by the 4LI with the vector control system is demonstrated by the experimental results. Besides, the independent position drive is demonstrated.
