FastTrans - Insulation stressed with fast rise time repetitive voltages from high voltage power electronics
High voltage power electronic converters are central elements in the physical infrastructure of any flexible energy system because they enable effective switching and seamless control of the power flow between the different suppliers and consumers in the electric power grid. However, the rapid switching of power electronic converters cause voltage surges with fast rise times that can inflict more severe stress on the insulation of electrical apparatus than traditional stress caused by pure sinusoidal voltages.
