英语翻译
1） it has inherent advantages of CSI ：short-circuit protection because of the out current being limited by the regulated dc-link current
2） the use of the buck converter enables reduction of the dc-link inductor size
3）The angle is actively controlled by adjusting the gating instant of the LCI.
