Scope
This part of GB/T 12668 applies to general-purpose AC variable-speed drive systems, which include power converters, control equipment and one or more electric motors. Not suitable for traction drives and electric vehicle drives. This part applies to electrical drive systems (PDS) connected to an AC power supply voltage below 1kV, 50Hz or 60Hz, and a load-side frequency up to 600Hz. Electromagnetic compatibility (EMC) characteristics are included in IEC 61800-3. This part gives the characteristics of the converter and its relation to the whole AC drive system. At the same time, the performance requirements of the converter rating, normal service conditions, overload conditions, surge withstand capacity, stability, protection, AC power grounding and testing are described. In addition, this standard discusses application guidelines such as control schemes, diagnostics and topology.
