Abstract
In this work, a dual three-phase Interior Permanent Magnet Synchronous Machine (IPMSM) drive connected to a high voltage DC/DC converter (800 V) at its input is considered for electric vehicle (EV) applications. The drive is constituted by two cascaded three-phase inverters, enabling fast charging capabilities. In this particular configuration, balancing the input voltages of the two inverters is mandatory during operation. A novel control approach that not only provides such voltage balancing but also considers the cross-coupling effects of the dual-three phase IPMSM is proposed, guaranteeing an adequate torque regulation through the whole operation range of the drive. Simulation results, generated by means of a high fidelity platform, are provided to validate the proposed approach. Additionally, preliminary experimental results are also included.
