This paper introduces a simplified method for estimating switching energy losses in an IGBT device of a Voltage Source Converter (VSC) using Electro-Magnetic Transient (EMT) simulations. By considering the switching process as characterized by an equivalent circuit model of a unit cell that represents one leg of a VSC, equations are derived to evaluate the switching losses at different load currents. The computational effort needed to estimate switching loses with the proposed method is much… CONTINUE READING
