Stability enhancement methodologies for slim dc-link Drives

Project Details


The faster growth of demand for electricity has exerted pressure on power electronics industry to take their systems design to a whole new level. Electrical motor drive systems as consumers of considerable amount of global electrical energy are none exceptions. Passive components incorporated for filtering purposes are one of the main obstacles in this way which have slowed down the development process. DC-link filter as an essential part of the motor drive systems can significantly influence the system cost, reliability and power quality. Moving towards more reliable and cost-effective motor-driven applications has made the manufacturers to employ a small dc-link capacitor. However, utilizing small dc-link film capacitor limits the performance of the drives which can make them more susceptible to grid impedance variation and possible instable operation.
The aim of this study is to come up with a systematic design methodology to model drive behavior under different conditions for stability analysis and consequently propose an effective instability compensation solution/s to maintain the performance of motor drive.
