BS EN IEC 62909-1:2025

This standard BS EN IEC 62909-1:2025 Bi-directional grid-connected power converters is classified in these ICS categories:

• 29.200 Rectifiers. Converters. Stabilized power supply

IEC 62909-1:2025 specifies general and safety aspects of bi-directional grid-connected power converters (GCPC), consisting of a grid-side inverter with two or more types of DC power ports on the application side with system voltages not exceeding 1 000 V AC or 1 500 V DC. This document can also be used for the special case of a multiple DC power port GCPC used in an application requiring only one DC power port. This document considers general aspects such as terminology, specifications, performance, system architecture, as well as safety requirements. This document does not cover: - uninterruptible power supply (UPS) systems, which fall under the scope of the IEC 62040 series, - power conversion equipment for use in photovoltaic systems, which fall under the scope of the IEC 62109 series, and - bi-directional power converters to charge or discharge the batteries located within electric vehicles or in the charging station, which fall under the scope of the IEC 61851 series. NOTE 1 The external system (e.g. energy management system, utility operations system) is not defined in this document. NOTE 2 The power converter sub-system case for use in electrical energy storage systems is currently covered by this document but will be covered by the IEC 63285 series (under preparation). NOTE 3 Annex A provides examples of GCPCs. These examples contain GCPCs covered and not covered by this document. This second edition includes the following significant technical changes with respect to the previous edition: a) the title has been changed by adding the wording "and safety"; b) the scope has been changed in order to clarify the bi-directional grid-connected power converters (GCPCs) covered by this document.
