IEC 62093:2022 PDF Download

A requirement for the design qualification of power conversion equipment (PCE) used in terrestrial photovoltaic (PV) systems is outlined in the International Electrotechnical Commission standard IEC 62093:2022.

The standard includes a variety of electronic power conversion equipment used in PV applications and is relevant to PCE used in both indoor and outdoor environments. DC-to-AC power conversion devices, DC-to-DC converters, battery charger converters, and battery charge controllers are all included in this. The standard is applicable to PCE coupled to PV arrays with maximum circuit voltages no higher than 1,500 V DC.

The standard's second version, which was released in 2022, has a number of revisions from the first edition. The title update, which emphasizes the design qualification of power conversion electronics (PCE) and excludes qualifying testing for other system components, is the first important change. The standard now only covers power conversion equipment and no longer includes balance-of-system components, among other notable revisions to clause headings.

Additionally, the test methodologies are altered in the second edition; however, the specifics of these modifications are not covered in the offered description.
