Abstract:

Power converters are essential to green energy transition. The converter consists of active and passive components. The size, weight, and volume of the drive are decided by the passive components. They may typically contribute to 75% of the weight and volume of the converter. For these converters, dc-link capacitor is the major contributor among the passive components. To reduce the size of converters, reduction in value of dc-link capacitance is an alternative. Such alternate converters can be classified as small dc-link capacitor-based power converters. The lecture focuses on conventional power converters (two-level and three-level converters) with small dc-link capacitor and related issues such negative impedance instability, mid-point voltage balance in three-level converter. Furthermore, the lecture also discusses some small dc-link capacitor-based power converter topologies which utilize current injection circuits for grid-connected application. These converters have advantage of high efficiency and high power density.
