Multimedia systems and equipment - Colour measurement and management - Part 12-2: Simple metadata fo...
IEC 61966-12-2:2024 specifies the colour gamut metadata format for video systems intended for use in CE (consumer electronics) devices. The metadata specified in this part of IEC 61966-12 is limited to the gamut description for display types comprising the three primary additive colours, whose white and black points have the same chromaticity. It is fundamentally based on the conventional VESA-…
Unified power flow controller (UPFC) installations - System tests
IEC TR 63500:2024 provides the general information, items, conditions, and evaluation of test results for on-site system tests of unified power flow controller (UPFC) installations based on modular multi-level converter (MMC) technology. For special functions or performances that are claimed by specific projects, some extra test items not included in this document can be added according to the…
Thermal standardization on semiconductor packages - Part 2-1: 3D thermal simulation models of semico...
IEC 63378-2-1:2024 specifies three-dimensional (3D) thermal models of discrete semiconductor packages (TO-243, TO-252 and TO-263), utilized in the steady-state thermal analysis of electronic devices to estimate junction temperatures accurately.
This model is assumed to be made by semiconductor suppliers and to be used by assembly makers of electronic devices.
Semiconductor devices - Part 15: Discrete devices - Isolated power semiconductor devices
IEC 60747-15:2024 gives the requirements for isolated power semiconductor devices. These requirements are additional to those given in other parts of IEC 60747 for the corresponding non-isolated power devices and parts of IEC 60748 for ICs. This third edition includes the following significant technical changes with respect to the previous edition:
a) The intelligent power semiconductor modules…
Dispositifs à semiconducteurs - Partie 15: Dispositifs discrets - Dispositifs de puissance à semicon...
L'IEC 60747-15:2024 spécifie les exigences relatives aux dispositifs de puissance à semiconducteurs isolés. Ces exigences s’ajoutent à celles qui figurent dans d’autres parties de l’IEC 60747 pour les dispositifs de puissance non isolés correspondants et dans des parties de l’IEC 60748 pour les circuits intégrés. Cette troisième édition inclut les modifications techniques majeures suivantes…
Scope
1.1 These requirements cover power banks, sometimes also known as portable USB chargers or
portable back-up battery power, which are standalone devices that incorporate primary or secondary
batteries for mobile powering of low voltage electronic devices.
1.2 These requirements cover products with the following power characteristics:
a) Input:
1) Supplied by isolated dc power source…
This document specifies requirements for implementations of the C++ programming language. The first such requirement is that they implement the language, so this document also defines C++. Other requirements
and relaxations of the first requirement appear at various places within this document.
C++ is a general purpose programming language based on the C programming language as described in
