Abstract Open-end winding (OEW) load fed by dual converters is an effective type of multi-level converter, and its redundant space vectors can improve system reliability. Dual three-level (3L) converters can achieve the output characteristics of five-level (5L) converters. However, the pulse width modulation (PWM) strategies of five-level converters applied to dual 3L converters are complex and computationally expensive. This paper provided an implementation method that extends the 3L improved virtual space vector PWM (IVSVPWM) to dual 3L converters. The zero sequence voltage (ZSV) was eliminated, and the common mode voltage (CMV) was suppressed to 16.7% of the DC power supply. The neutral point voltage (NPV) of dual 3L converters was adjusted actively and accelerated by modifying neutral point currents in the 3L-IVSVPWM. The proposed modulation strategy can maintain the same computation amount as the single 3L strategy. Simulation and experimental results show that the proposed dual 3L modulation strategy extended from 3L-IVSVPWM can eliminate ZSV, suppress CMV, and actively control NPV under the whole modulation system and any load power factor.
