| Abstract |
Tap changer converter periodically connects and disconnect transformer tap hereby achieving continuous voltage regulation. Commutation cell with bi-directional switch and high frequency switching is a basic building element. Used technique requires additional inductances or use accurate current measurement and has potential hazards. Different solutions are suggested in the paper and verified by simulation and experimental study. For tap changer converter commutation it is important that the commutation is symmetrical. A symmetrical smart commutation technique without necessity to measure current is developed and presented. Experiments verify the simulation results. The application of such a commutation is demonstrated on 500kVA tap changed transformer. Voltage regulation with tap changer is demonstrated too. |
