This study optimizes shared DC-links in dual-inverter systems feeding poly-stator machines by exploiting carrier and modulation phase shifts. The goal is to reduce RMS current, enabling a compact DC-link while meeting lifetime and maximum emissions requirements. A fast MATLAB-based current reconstruction method generates a global RMS mapping for joint converter–machine design. Simulink simulations validate the DC-link gain across different machine configurations without degrading THD.
