Abstract In two-level three-phase voltage source inverter,both dead-time and minimum pulse- width limitation(MPWL) narrow down the practical voltage space,which results in the invalidation of the conventional space vector pulse-width modulation(PWM) and related over-modulation methods. A novel integrated PWM(IPWM) strategy is proposed with dead-time and MPWL considered. First,the strategy combines the classical seven-segment SVPWM with five-segment DPWM1,three-segment PWM and one-segment PWM,redefines the linear-modulation region and the over-modulation region and increases the practical voltage space. Second,the strategy decreases the calculation time and reduces total harmonic distortion(THD) with the optimum over-modulation method,while it improves the output voltage linearity by the reference voltage linearization. Additionally,the strategy presents the inserting method of the new dead-time based on finite state machine. Finally,confirmatory experimental results on induction motor valid the IPWM strategy and illustrates its excellent performance.
