Standard history
IEC 61800-2:2021 applies to adjustable speed electric AC power drive systems, which include semiconductor power conversion and the means for their control, protection, monitoring, measurement and the AC motor. It applies to adjustable speed electric power drive systems intended to feed AC motors from a BDM or CDM connected to line-to-line voltages up to and including 35 kV AC 50 Hz or 60 Hz and/or voltages up to and including 1,5 kV DC input side. NOTE Adjustable speed electric DC power drive systems intended to feed DC motors are covered by IEC 61800-1. This documents defines and describes a non-exhaustive list of criteria for the selection of BDM/CDM/PDS performance and functional attributes. This list is reviewed by the responsible parties to determine considerations for the design of device(s), equipment or system(s) with related testing specification. It also suggests a selection of performance and functional attributes for driven equipment and extended products. The performance and functional attributes focus on the following categories: - principal parts topology and classification of the PDS; - ratings, performance and functionality; - specifications for the environment in which the PDS is intended to be installed and operated; - other specifications which might be applicable when specifying a complete PDS. Traction applications and electric vehicles are excluded from the scope of this document. This document provides a non-exhaustive list from which minimum requirements can be used for the development of a specification between customer and manufacturer based on the application requirements. This same non-exhaustive list can be used by a manufacturer to determine the minimum requirements for a commoditised BDM/CDM/PDS without customer interaction based on the specified application of that BDM/CDM/PDS. This third edition cancels and replaces the second edition published in 2015. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a. the requirements from IEC 61800-4 for high-voltage PDS are now merged with requirements from IEC 61800-2:2015; b. Clause 1 has been updated to introduce the new concept of Clause 4; c. terms and definitions in Table 1 to Table 4 have been classified in logical order; classification in low voltage and high voltage has been considered in Table 5, and Figure 3 clarifies boundaries within BDM/CDM/PDS. d. Clause 4 is new and creates the methods for evaluating a product to this document; e. Clause 5 has been updated with respect to: 1) specific content for high-voltage BDM/CDM/PDS; 2) description of the basic topology for BDM/CDM/PDS (5.2); 3) ratings and performance (5.3 and 5.4); 4) reference to applicable standards within the IEC 61800 series with respect to EMC (IEC 61800-3), electrical safety (IEC 61800-5-1), functional safety (IEC 61800-5-2), load duty aspects (IEC TR 61800-6), communication profiles (IEC 61800-7 series), power interface voltage (IEC TS 61800-8), and ecodesign (IEC 61800-9 series) to avoid conflicting requirements (5.5, 5.6, 5.7, 5.10, 5.11, 5.12); 5) update of requirement for ecodesign (5.8); 6) update of requirement for environmental evaluation (5.9); 7) implementation of requirement for explosive atmosphere (5.14); f) Clause 6 has been updated with test requirement in order to provide a clear link between design requirement and test requirement; g) Clause 7 has been updated to harmonize the marking and documentation requirement within IEC 61800 (all parts); h) existing Annex A and Annex B have been updated to include specific detail pertaining to high voltage BDM/CDM/PDS.
