Safety requirements for power electronic converter systems and equipment - Part 1: General
IEC 62477-1:2022 applies to power electronic converter systems (PECS), any specified accessories, and their components for electronic power conversion and electronic power switching, including the means for their control, protection, monitoring and measurement, such as with the main purpose of converting electric power, with rated system voltages not exceeding 1 000 V AC or 1 500 V DC. This document also applies to PECS which intentionally emit or receive radio waves for the purpose of radio communication. This document can also be used as a reference standard for product committees producing product standards for: - adjustable speed electric power drive systems (PDS); - standalone uninterruptible power systems (UPS); - low voltage - stabilized DC power supplies; - bidirectional power converters. For PECS and their specified accessories for which no product standard exists, this document provides minimum requirements for safety aspects. This document has the status of a group safety publication in accordance with IEC Guide 104 for power electronic converter systems for solar, wind, tidal, wave, fuel cell or similar energy sources. According to IEC Guide 104, one of the responsibilities of technical committees is, wherever applicable, to make use of basic safety publications and/or group safety publications in the preparation of their product standards. Guidance for use of this group safety publication for product committees is given in Annex S. This document - establishes a common terminology for safety aspects relating to PECS, - establishes minimum requirements for the coordination of safety aspects of interrelated parts within a PECS, - establishes a common basis for minimum safety requirements for the PECS portion of products that contain PECS, - specifies requirements to reduce risks of fire, electric shock, thermal, energy and mechanical hazards, during use and operation and, where specifically stated, during service and maintenance, and - specifies minimum requirements to reduce risks with respect to PECS designed as pluggable and permanently connected equipment, whether it consists of a system of interconnected units or independent units, subject to installing, operating and maintaining the PECS in the manner prescribed by the manufacturer. This document does not cover - telecommunications apparatus other than power supplies to such apparatus, - functional safety aspects as covered by, for example, IEC 61508 (all parts), and - electrical equipment and systems for railways applications and electr

Exigences de sécurité applicables aux systèmes et matériels électroniques de conversion de puissance - Partie 1: Généralités
L'IEC 62477-1:2022 s'applique aux systèmes électroniques de conversion de puissance (PECS), à tout accessoire spécifié, ainsi qu'à leurs composants pour la conversion de puissance électronique et la commande (ouverture et fermeture) électronique de puissance, y compris les moyens de commande, de protection, de surveillance et de mesure, qui ont pour principale fonction la conversion de puissance électrique, d'une tension système assignée qui ne dépasse pas 1 000 V en courant alternatif ou 1 500 V en courant continu. Le présent document s'applique également aux PECS qui émettent ou reçoivent intentionnellement des ondes radioélectriques à des fins de radiocommunication. Le présent document peut également être utilisé comme norme de référence par les comités de produits qui élaborent des normes de produits applicables aux:
systèmes d'entraînement électrique de puissance à vitesse variable (PDS, Power Drive Systems);
alimentations sans interruption (ASI) autonomes;
alimentations stabilisées basse tension en courant continu;
convertisseurs de puissance bidirectionnels. Pour les PECS et leurs accessoires spécifiés pour lesquels il n'existe pas de norme de produits, le présent document spécifie des exigences minimales pour les aspects de sécurité. Le présent document a le statut d'une publication groupée de sécurité conformément au Guide 104 de l'IEC applicable aux systèmes électroniques de conversion de puissance pour énergie solaire, éolienne, des marées, des vagues, des piles à combustible ou sources d'énergie analogues. Conformément au Guide 104 de l'IEC, il incombe aux comités d'études d'utiliser, dans toute la mesure du possible, les publications fondamentales de sécurité et/ou les publications groupées de sécurité pour l'élaboration de leurs normes de produits. Les recommandations relatives à l'utilisation de la présente publication groupée de sécurité pour les comités de produits sont données à l'Annexe S. Le présent document
établit une terminologie commune applicable aux aspects de sécurité concernant les matériels et les PECS,

Varnostne zahteve za močnostne elektronike pretvorniške sisteme in opreme - 1. del: Splošno (IEC 62477-1:2022)
Ta del standarda IEC 62477 se nanaša na močnostne električne pretvorniške sisteme (PECS), posebno dodatno opremo in njihove dele za električno močnostno pretvorbo in električno močnostno preklapljanje, vključno s sredstvi za njihov nadzor, zaščito, spremljanje in merjenje, kot z glavnim namenom za pretvorbo električne energije z nazivnimi sistemskimi izmeničnimi napetostmi največ 1000 V oziroma sistemskimi enosmernimi napetostmi največ 1500 V.
Ta dokument se uporablja tudi za električne močnostne pretvorniške sisteme, ki namenoma oddajajo ali sprejemajo radijske valove za namene radijske komunikacije.
Ta dokument lahko kot referenčni standard uporabljajo odbori za proizvode, ki pripravljajo standarde za proizvode za:
• električne pogonske sisteme z nastavljivo hitrostjo (PDS);
• samostojne sisteme za neprekinjeno napajanje (UPS);
• nizkonapetostne napajalnike za stabilizirano napajanje z enosmernim tokom;
• dvosmerne močnostne pretvornike.
Ta dokument določa minimalne varnostne zahteve za močnostne električne pretvorniške sisteme in njihovo posebno dodatno opremo, ki nimajo določenega standarda za proizvod.
Ta dokument ima status publikacije skupinske varnosti, ki je v skladu z vodilom IEC 104 za električne močnostne pretvorniške sisteme na osnovi sonca, vetra, plimovanja, valovanja, gorivnih celic ali podobnih virov.
Glede na vodilo IEC 104 je ena od dolžnosti tehničnih odborov, da pri pripravi standardov za proizvode uporabijo osnovne varnostne publikacije in/ali publikacije skupinske varnosti, če je to mogoče.
Napotki za uporabo te publikacije skupinske varnosti za odbore za proizvode so podani v dodatku S.
Ta dokument
• vzpostavlja skupno terminologijo za varnostne vidike v zvezi z močnostnimi električnimi pretvorniškimi sistemi,
• določa minimalne zahteve za usklajevanje varnostnih vidikov medsebojno povezanih delov znotraj močnostnih električnih pretvorniških sistemov,
• vzpostavlja skupno osnovo za minimalne varnostne zahteve za tiste delov proizvodov, ki vsebujejo močnostne električne pretvorniške sisteme,
• določa zahteve za zmanjšanje tveganja požara, električnega udara, toplotnih, energijskih in mehaničnih tveganj med uporabo, delovanjem ter, kjer je to navedeno, popravilom in vzdrževanjem, in
• določa minimalne zahteve za zmanjšanje tveganja v zvezi z močnostnimi električnimi pretvorniškimi sistemi, zasnovanimi kot oprema, ki se priklopi ali je stalno priklopljena, če je sestavljena iz sistema vzajemno povezanih enot ali samostojnih enot, upoštevajoč namestitev, uporabo in vzdrževanje močnostnih električnih pretvorniških sistemov, na način, ki ga je predpisal proizvajalec.
Ta dokument ne zajema:
• telekomunikacijskih naprav, ki niso napajalniki teh naprav,
• funkcionalne varnosti, ki jo zajema na primer standard IEC 61508 (vsi deli), in
• električne opreme in sistemov za uporabo pri železnici in za elektronska vozila.
