This letter proposes a unified space vector pulse width modulation (SVPWM) for a dual two-level inverter system with two isolated dc voltage sources. The gate pluses for the dual inverter are generated by the concept of one unified SVPWM in accordance with the voltage-second integral principle and the ratio of the two dc-link voltages can be an arbitrary positive value. This proposed technique also...
A coordinated space vector modulation (SVPWM) algorithm without sector identifications is proposed for the dual inverter fed open winding interior permanent magnet synchronous motor (IPMSM) system, where the duty ratios of the three phases for each inverter are directly calculated, and no trigonometric function calculations or sector identifications are involved. Moreover, the switching frequency...
