Six-phase vehicular drive with renewable dc sources and hybrid PWM control of four inverters

The paper presents results of research of quad-inverter-based automotive system with combined scheme of PWM control of inverters, supplied by two renewable dc sources (by fuel cells and by battery). It has been shown, that hybrid switching techniques can be used successfully for control of vehicle drive with non-equal (variable) voltages of dc-links. Results of modeling proved the fact of symmetries of waveforms of the phase voltages of the system for any operating conditions.
