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.

This standard defines procedures for transferring power to non-powered IoT devices using the existing ISM band communication infrastructure and RF WPT and a protocol for a two-way, long-distance wireless network in which IoT devices and APs communicate using backscatter modulation of ISM-band signals. Three components are required for two-way, long-distance wireless communication using backscatter modulation of ISM-band signals: an STA that transmits wireless power and data packets to SSNs by forming ISM-band signal channels between HIE-APs, a batteryless SSN that changes the sensitivity of the channel signals received from the STA using backscatter modulation, and an HIE-AP that practically decodes the channel signals whose sensitivity was changed by the SSN. In this standard, the procedures for CW-type RF WPT using communication among these three components are specified based on application of the CSI or RSSI detection method of ISM-band communication. This standard proposes a convergence communication protocol than can deploy sensors, which can operate at low power (dozens of microwatts or less) without batteries, collect energy, and perform communication, to transmit power to SSNs using RF WPT based on parasitic communication. This method can be applied to application service areas such as domestic IoT, the micro-sensor industry, and industries related to environmental monitoring in the future

IEC TR 62543:2022 is available as IEC TR 62543:2022 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
IEC TR 62543:2022 gives general guidance on the subject of voltage sourced converters (VSC) used for transmission of power by high voltage direct current (HVDC). It describes converters that are not only voltage sourced (containing a capacitive energy storage medium and where the polarity of DC voltage remains fixed) but also self-commutated, using semiconductor devices which can both be turned on and turned off by control action. The scope includes 2‑level and 3-level converters with pulse-width modulation (PWM), along with multi-level converters, modular multi-level converters and cascaded two-level converters, but excludes 2‑level and 3-level converters operated without PWM, in square-wave output mode. HVDC power transmission using voltage sourced converters is known as "VSC transmission". The various types of circuit that can be used for VSC transmission are described in this document, along with their principal operational characteristics and typical applications. The overall aim is to provide a guide for purchasers to assist with the task of specifying a VSC transmission scheme. Line-commutated and current-sourced converters are specifically excluded from this document. This edition includes the following significant technical changes with respect to the previous edition:
- in Clause 3, some redundant definitions which were identical to those listed in IEC 62747 have been deleted;
- in 4.3.4, description and diagrams have been added for the cases of a bipole with dedicated metallic return and a rigid bipole;
- in 4.4, mention is made of the bi-mode insulated gate transistor (BiGT) and injection enhanced gate transistor (IEGT) as possible alternatives to the IGBT;
- in 5.6, the reference to common-mode blocking reactors has been deleted since these are very rarely used nowadays.

This document describes a kind of water cooling system, in which de-ionized water or de-ionized water mixed with other solutes is used as the heat transfer agent for the removal of heat from power electronic equipment. Water cooling system can be separated into main circuit, and control and protection system. Other cooling systems, in which de-ionized water is not the heat transfer agent, are excluded in this document.
This document provides guidance and supporting information for both purchaser(s) and potential supplier(s). It can be used as the basis for drafting a procurement specification and as a guide during project implementation.

This International Standard defines terms for the subject of self-commutated voltage-sourced converters used for transmission of power by high voltage direct current (HVDC). The standard is written mainly for the case of application of insulated gate bipolar transistors (IGBTs) in voltage sourced converters (VSC) but may also be used for guidance in the event that other types of semiconductor devices which can both be turned on and turned off by control action are used. Line-commutated and current-sourced converters for high-voltage direct current (HVDC) power transmission systems are specifically excluded from this standard.

This part of IEC 61243 is applicable to portable voltage detectors, with or without built-in power
sources, to be used on electrical systems for voltages of 1 kV to 800 kV AC, and frequencies
of 50 Hz and/or 60 Hz.
This document applies only to voltage detectors of capacitive type used in contact with the bare
part to be tested, as a complete device including its insulating element or as a separate device,
adaptable to an insulating stick which, as a separate tool, is not covered by this document
(see 4.4.2.1 for general design).
Other types of voltage detectors are not covered by this document.
NOTE Self ranging voltage detectors (formally "multi range voltage detectors") are not covered by this document.
Some restrictions or formal interdictions on their use are applicable in case of switchgear of
IEC 62271 series design, due to insulation coordination, on overhead line systems of electrified
railways (see Annex B) and systems without neutral reference. For systems without neutral
reference, the insulating level is adapted to the maximum possible voltage to the earth (ground).
Products designed and manufactured according to this document contribute to the safety of
users provided they are used by persons trained for the work, in accordance with the hot stick
working method and the instructions for use.
Except where otherwise specified, all the voltages defined in this document refer to values of
phase-to-phase voltages of three-phase systems. In other systems, the applicable phase-tophase
or phase-to-earth (ground) voltages are used to determine the operating voltage.

This edition includes the following significant technical changes with respect to the previous edition: a) The scope is more precise, stating that only bare contact to the part to be tested is reliable for these contact voltage detectors. The rationale is that tests on painted or coated conductors have led to wrong indications, as this non-conductive paint or coat acts as a capacitor with different capacity according to the thickness. This capacity has an effect on the threshold voltage. b) A contact probe is introduced as a new type of non-conductive contact electrode. c) A new type "exclusively outdoor type" has been defined and implemented into the requirements and test procedure. d) A selector for voltage and frequency is allowed if foreseeable misuse is excluded. e) The marking for voltage detectors with low interference voltage has been made more precise. f) The indication groups have been made more precise and requirements and tests for the "ready to operate state" and "stand-by state" added. g) Requirements and tests for electromagnetic compatability have been implemented. h) An example for good electrical connection for the tests is introduced.
