电流源空间矢量PWM逆变器的重叠时间补偿方法

In voltage-source inverters, it is necessary to add the dead time between gating signals of the upper and lower switches to prevent short circuit in a phase leg. But in current-source inverters (CSI), due to the large series inductor in dc link, it is necessary to add the overlap time in gating signals of switches during the commutation process for avoiding voltage spikes generated by the intermit...
