What does EU Regulation 428/2009 mean for inverters?

And in December 2014, the EU implemented amendments (Annex I) to its dual-use regulation 428/2009, addressing frequency converters (aka converters or inverters). The EU regulation controls the export of drives that have the following performance characteristics: frequency control better (less) than 0.2 %.

Why do IBRS rely on inverters?

In contrast with conventional synchronous generation resources, IBRs rely on inverters to turn their DC electrical output into AC power so that it can be sent to the grid.[v] An inverter is a power electronic device that transforms DC power to AC power.

What is an inverter & how does it work?

An inverter is a power electronic device that transforms DC power to AC power. IBRs present new opportunities but can also introduce new operational challenges and potential reliability risks to the electric system as it currently operates. In certain circumstances, IBRs can behave differently than synchronous generation.
