Applies high AC or DC voltages to verify insulation integrity between high-voltage circuits and earth ground.
IEC 62477-2, developed by the International Electrotechnical Commission (IEC), is titled "Safety requirements for power electronic converter systems and equipment – Part 2: Power electronic converters from 1000 V AC or 1500 V DC up to 1500 V AC or 2000 V DC" .
If you have been searching the internet for a , you are likely an electrical engineer, compliance manager, or procurement specialist trying to understand the specific safety requirements for power electronic converter systems.
For specific application questions, you may want to search for the IEEE PCIC conference paper on applying the standard to high voltage ASDs , which provides practical insights.
Adjustable speed electrical power drive systems (PDS).
The standard mandates comprehensive protection against electric shock. This involves classifying circuits into (DVC A, B, and C) to determine the necessary levels of insulation and isolation. Requirements cover basic protection, fault protection (e.g., grounding), enhanced protection, and specific measures like capacitor discharge for safety.
: It protects companies from lawsuits if an accident happens.
You must read IEC 62477-1 first, then apply the modifications and additions in Part 2 . If you only have Part 1, you are not compliant for DC-specific equipment.
