中文摘要	A space vector pulse-width modulation (SVPWM) strategy was developed to avoid the failure of dead-time compensation near the zero-current point, A two-phase modulation method is used, with the null switching state in each sector selected according to the power factor angle. As a result, when the current is passing zero, the corresponding phase does not commute and dead-time compensation is avoided, thus, the system does not have to detect the current direction. Test results show that the strategy effectively compensates for dead-time effects, even near the zero-current point. Furthermore, switching actions are reduced to 66.7% of the three-phase modulation methods, which leads to lower switching losses. The method is easy to implement and can be widely applied.
