IEC 62040-3:2021(E) establishes the performance and test requirements applied to movable, stationary and fixed electronic uninterruptible power systems (UPS) that
- are supplied from AC voltage not exceeding 1 000 V,
- deliver AC output voltage not exceeding 1 000 V,
- incorporate an energy storage device not exceeding 1 500 V DC, and
- have a primary function to ensure continuity of load power.
This document specifies performance and test requirements of a complete UPS and, where applicable, of individual UPS functional units. This document also includes UPS performance and test requirements related to UPS switches that interact with UPS functional units to maintain continuity of load power.
This document does not cover
- conventional AC and DC distribution boards and their associated switches,
- stand-alone static transfer systems covered by IEC 62310-3,

This document applies to all line-commutated high-voltage direct current (HVDC) converter
stations used for power exchange (power transmission or back-to-back installation) in utility
systems. This document presumes the use of 12-pulse thyristor converters but can, with due
care, also be used for 6-pulse thyristor converters.
In some applications, synchronous compensators or static var compensators (SVC) may be
connected to the AC bus of the HVDC converter station. The loss determination procedures
for such equipment are not included in this document.
This document presents a set of standard procedures for determining the total losses of an
HVDC converter station. The procedures cover all parts, except as noted above, and address
no-load operation and operating losses together with their methods of calculation which use,
wherever possible, measured parameters.
Converter station designs employing novel components or circuit configurations compared to
the typical design assumed in this document, or designs equipped with unusual auxiliary
circuits that could affect the losses, are assessed on their own merits.

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 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 in Annex A as to how to
extend the results to certain other types of MMC building block configuration.
The standard is written mainly for insulated gate bipolar transistors (IGBTs) but may also be
used for guidance in the event that other types of turn-off semiconductor devices are used.
Power losses in other items of equipment in the HVDC station, apart from the converter
valves, are excluded from the scope of this standard.
This standard does not apply to converter valves for line-commutated converter HVDC
systems.
