Scope

This document specifies the classification, operating conditions, functions, performance, protection, test methods, inspection rules, marking, packaging, transportation, and storage of power electronic systems for hydrogen production by electrolysis of water. This document applies to power electronic systems such as rectifiers and DC/DC converters with a DC output voltage not exceeding 1500V in hydrogen production systems by electrolysis of water. 1. Standard Structure This document specifies the classification, operating conditions, functions, performance, protection, test methods, inspection rules, marking, packaging, transportation, and storage of power electronic systems for hydrogen production by electrolysis of water. 2. Scope of Application This document applies to power electronic systems such as rectifiers and DC/DC converters with a DC output voltage not exceeding 1500V in hydrogen production systems by electrolysis of water. 3. Terms and Definitions The standard proposes 14 terms related to power electronic systems for hydrogen production by electrolysis of water, and clearly defines their definitions and scope. 4. Classification The standard classifies systems according to the form of the hydrogen production system bus and the type of converter, as well as the output control method. It is divided into two categories based on the form of the hydrogen production system bus and the type of converter: rectifier power supply and DC/DC converter power supply; and according to the type of output control method: output DC current control, output DC voltage control, and output DC power control. 5. Operating Conditions This section specifies the operating environment conditions for power electronic systems for hydrogen production by electrolysis of water, including hydrogen production rectifiers and hydrogen production DC/DC converters. 6. Functional Requirements This section specifies the general requirements, temperature rise, communication and human-mach
