183 FOREWORD
184 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
185 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
186 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
187 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
188 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
189 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
190 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
191 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
192 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
193 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
194 consensus of opinion on the relevant subjects since each technical committee has representation from all
195 interested IEC National Committees.
196 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
197 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
198 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
199 misinterpretation by any end user.
200 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
201 transparently to the maximum extent possible in their national and regional publications. Any divergence between
202 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
203 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
204 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
205 services carried out by independent certification bodies.
206 6) All users should ensure that they have the latest edition of this publication.
207 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
208 members of its technical committees and IEC National Committees for any personal injury, property damage or
209 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
210 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
211 Publications.
212 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
213 indispensable for the correct application of this publication.
214 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
215 rights. IEC shall not be held responsible for identifying any or all such patent rights.

236 INTRODUCTION
237 In order to optimize power consumption, for example, within the home power management, it is
238 necessary to optimally combine electricity generation with rechargeable energy storage. This
239 optimization is accomplished, in part, by providing an efficient transfer between DC and AC
240 electricity to accommodate storage batteries. IEC 62909 standards describe a bidirectional grid-
241 connected power converter (GCPC) efficiently connected for example to sources of power
242 generation and energy storage.
243 IEC 62909-1 defines common general requirements, independent from the special
244 characteristics of individual applications. IEC 62909-2 defines the additional requirements
245 necessary for interfacing particular types of distributed energy resources to a GCPC. IEC
246 62909-3 presents the EMC requirements for GCPC.
247 GCPCs can be connected to multiple kinds of distributed energy resources. While there are
248 EMC requirements for power electronic converters for single distributed energy resources, for
249 example solar systems or battery storage systems, those requirements are in some cases
250 different from each other. Hence, it is necessary to clarify which requirements should be applied
251 to the various types of GCPCs.

253 BI-DIRECTIONAL GRID CONNECTED POWER CONVERTERS –
255 Part 3: EMC requirements and test methods
259 1 Scope
260 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
262 or more DC ports on the application side with system voltages not exceeding 1 000 V AC or 1
263 500 V DC.
265 This document may also be used for special cases of GCPCs with only one DC port, where:
266 - GCPC with multiple physical DC ports is used in an application requiring only one DC port, or
267 - no dedicated product standard for such a single DC port GCPC is available.
269 This document considers GCPCs in both residential and non-residential environments.
271 This document does not cover:
272 - uninterruptible power supply (UPS) systems, which fall under the scope of IEC 62040 (all parts).
273 - power conversion equipment covered by IEC 62920, i.e. GCPCs for use in photovoltaic power
274 systems with or without DC-coupled electrical energy storage devices
275 - power converters to charge batteries within electric vehicles (EVs) which fall under the scope of
276 IEC 61851-21-2
278 NOTE 1 Annex A provides examples of GCPCs covered and not covered by this document.
279 NOTE 2 The Power Converter Subsystem (PCSS) for use in Electrical Energy Storage Systems (EESS) will be
280 referenced in a future publication of IEC 63285. In that case, that PCSS will be added to the bulleted items above.
