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 document is applicable to eye, face and head protectors used in work where there is a risk of exposure to an electric arc hazard. Such protectors consist of one or several devices (e.g. hood, goggles, balaclavas, face shields, helmets, etc.), which might need to be combined together in order to give protection to eye, face and head for the intended use. This document covers the performance requirements for protectors and single protective devices considering thermal, optical and mechanical hazards of an electric arc. Because of the limitations of test apparatus at very high energy arcs, no arc rating above 4 100 kJ/m2 (100 cal/cm2) can be assigned to protectors. This document does not cover protection against electric shock, noise, the consequences of physical and mental shock and the toxic influences caused by an electric arc. This document does not cover protectors for work intentionally using an electric arc, e.g. arc welding, plasma torch. This document does not cover face-screens for the reduction of an electric field inside conductive clothing in accordance with IEC 60895. Any other claims of the manufacturer for protection against other hazards to eye or face (e.g. welding radiation, hazards occurring during fire-fighting) are outside the scope of the document. Products designed and manufactured in accordance with this document contribute to the safety of the users provided they are used by skilled persons, in accordance with safe methods of work and the instructions for use.

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 third edition cancels and replaces the second edition published in 2003 and Amend-ment 1:2009. This edition constitutes a technical revision. 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.

IEC 61472-2:2021 specifies a method for determining the electrical component of the minimum approach distances for live working, for AC systems 1 kV up to and including 72,5 kV. This document addresses system overvoltages and the working air distances between equipment and/or workers at different potentials. The withstand voltage and minimum approach distances determined by the method described in this document can be used only if the following working conditions prevail:
workers are trained for, and skilled in, working live lines or close to live conductors or equipment;
the operating conditions are adjusted so that the statistical overvoltage does not exceed the value selected for the determination of the required withstand voltage;
transient overvoltages are the determining overvoltages;
tool insulation has no continuous film of moisture present on the surface;
no lightning is observed within 10 km of the work site;
allowance is made for the effect of the conducting components of tools.

This part of IEC 63245 specifies requirements for spatial wireless power transfer based on multiple magnetic resonances (SWPT-MMR), which is a non-radiative wireless power transfer (WPT). This document contains two categories of requirements: general requirements and functional requirements. The general requirements cover charging procedures and charging zones. The functional requirements cover each component of a SWPT-MMR system, such as transmitter coils.
