基于SVPWM的永磁同步电机驱动小直流母线电容串联IGBT斩波策略

In this letter, a series insulated-gate bipolar transistor (IGBT) chopping strategy based on space vector pulsewidth modulation (SVPWM) is proposed for a permanent magnet synchronous motor drive system with small dc-link capacitance and IGBT connected at the dc link. Based on the maximum output capability of the SVPWM technique, this letter clarifies the minimum dc-link voltage constraint based on...
