IEC 62751-2:2014 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 the case where each switch position consists of a number of turn-off semiconductor devices in series (topology also referred to as \'cascaded two-level converter\'). The main formulae are given for the two-level \'half-bridge\' configuration but guidance is also given as to how to extend the results to certain other types of MMC building block configuration.
