Standard history

This part of IEC 62909 specifies electromagnetic immunity and emission requirements of bi-261 directional grid-connected power converters (GCPCs) consiting of a grid-side inverter with two or more DC ports on the application side with system voltages not exceeding 1 000 V AC or 1 500 V DC.
This document may also be used for special cases of GCPCs with only one DC port, where:
- GCPC with multiple physical DC ports is used in an application requiring only one DC port, or
- no dedicated product standard for such a single DC port GCPC is available.
This document considers GCPCs in both residential and non-residential environments.
This document does not cover:
- uninterruptible power supply (UPS) systems, which fall under the scope of IEC 62040 (all parts).
- power conversion equipment covered by IEC 62920, i.e. GCPCs for use in photovoltaic power systems with or without DC-coupled electrical energy storage devices
- power converters to charge batteries within electric vehicles (EVs) which fall under the scope of IEC 61851-21-2
NOTE 1 Annex A provides examples of GCPCs covered and not covered by this document.
NOTE 2 The Power Converter Subsystem (PCSS) for use in Electrical Energy Storage Systems (EESS) will be referenced in a future publication of IEC 63285. In that case, that PCSS will be added to the bulleted items above.
