Scope

Scope: This document specifies the terms and definitions, symbols, technical requirements, test methods, inspection rules, marking, packaging, transportation, and storage for DC/DC converters used in low-voltage DC distribution networks (hereinafter referred to as DC/DC converters). This document applies to DC/DC converters with an input voltage range of 110V to 1500V DC. DC/DC converters for electrochemical energy storage systems can refer to this standard for use. This document does not apply to DC/DC converters that do not support bidirectional energy flow. Main Technical Content: This document specifies the requirements, test methods, inspection rules, marking, packaging, transportation, and storage for DC/DC converters used in low-voltage DC distribution networks (hereinafter referred to as DC/DC converters). This document applies to DC/DC converters connected to DC grids with voltage levels of 110V to 1500V. DC/DC converters for energy storage systems can refer to this standard for use, and DC/DC converters that do not support bidirectional energy flow are not applicable to this document. The main technical content of this document is as follows: (1) Terms and Definitions: The "Technical Specifications for DC/DC Converters in Low-Voltage DC Distribution Networks" is a recommended standard that inherits the terms and definitions from national and industry standards. This standard primarily references the terms and definitions defined in GB/T 3859.1-2013, GB/T 24347-2009, and DL/T 5044-2014. For a more accurate and comprehensive specification of the technical test methods for battery management systems, terms such as "rated output power," "peak output power," "dynamic response time," "nominal input voltage," and "rated output voltage" are defined in this standard. (2) Technical Requirements: The basic noise requirements for low-voltage DC distribution network DC/DC converters refer to related requirements such as GB/T 17478-2004 "Performance Characteri
