DC-Link Stabilization and Voltage Sag Ride-Through of Inverter Drives
2006 (English)In: IEEE transactions on industrial electronics (1982. Print), ISSN 0278-0046, Vol. 53, no 4, 1261-1268 p.Article in journal (Refereed) Published
Previous results concerning instability of the dc linkin inverter drives fed from a dc grid or via a rectifier are extended.It is shown that rectifier–inverter drives equipped with small (film)dc-link capacitors may need active stabilization. The impact oflimited bandwidth and switching frequency in the inverter–motorcurrent control loop is considered, and recommendations forselection of the dc-link capacitor, the switching frequency, andthe dc-link stabilization control law in relation to each other aregiven. This control law is incorporated in a field-weakening (toenhance voltage sag ride-through) current controller for whichdesign recommendations are presented.
