IEC 62477-2
is an essential international safety standard for high-voltage power electronic converter systems (PECS). It specifically addresses equipment with rated voltages from 1,000 V AC (or 1,500 V DC) up to 36 kV AC (or 54 kV DC) . Scope and Application

Pro tip:
Many companies buy a multi-user license (about 3x the single price) to legally place the IEC 62477-2 PDF on an internal server for all engineers. IEC 62477-2 is an essential international safety standard
5. The Pitfalls of "Obsolete" or "Unofficial" PDFs
- Comprehensive scope: Covers functional classes, electrical clearances/creepage, protective earthing, isolation, and protective devices for converters across many applications.
- Modern relevance: Addresses risks from high-frequency switching, double-insulated designs, and emerging converter topologies used in renewable energy and EV infrastructure.
- Clear safety criteria: Provides measurable limits and test procedures for dielectric strength, impulse withstand, and touch/proximity protection that manufacturers can apply consistently.
- Interoperability with other standards: Cross-references and aligns with IEC 62477-1, IEC 61558/60950 families where applicable, aiding certification and harmonization across product lines.
- Practical test guidance: Includes specified test voltages, durations, and environmental considerations that are applicable in lab certification workflows.
