12-pulse buck rectifier and partial power processing based converter for ultra-high power EV charging

With the rapid development of electrical vehicles (EV) and the trends in transportation electrification, the demand for fast charging facilities for electric vehicles is rising. <br/> <br/>In this thesis, a two-stage power electronics converter for DC fast battery charging application is designed and studied. A buck type 12-pulse converter with...

Cloud platform for EV charging management

Electric vehicle (EV) charging stations play an important role in the future development of the EV market. Uncoordinated charging will generate extra costs and bring unexpected stress to the grid. Multiple efficient charging strategies were proposed in past papers in order to solve the issues brought by uncoordinated charging. However, to put...

Algorithm for Determining the Hosting Capacity of Independent PV, or EV Charger Systems: In Industrial and Commercial LV Networks, with Respect to Slow Voltage Variations and Voltage Unbalances

In this thesis, an algorithm that calculates the hosting capacity of independent PV, or EV charger systems was created. The hosting capacity is based on slow voltage variations and voltage unbalances caused by worst case PV generation and EV charging scenarios. The algorithm was run for four different commercial and industrial networks, and a...
