Power losses in voltage sourced converter (VSC) valves for high-voltage direct current (HVDC) systems - Modular multilevel converters1 Scope This part of IEC 62751 gives the detailed method to be adopted for calculating the power losses in the valves for an HVDC system based on the modular multi level converter, where each valve in the converter consists of a number of self contained, two terminal controllable voltage sources connected in series. It is applicable both for the cases where each modular cell uses only a single turn off semiconductor device in each switch position, and
