Specification of Basic Requirements
1 Scope
This Part of GB/T 3859 specifies the performance of all semiconductor power converters and semiconductor power switches using controllable and/or non- controllable electronic valve devices.
The electronic valve devices mainly comprise semiconductor devices, including either not controllable (i.e.: rectifier diodes) or controllable (i.e.: various thyristors and power transistors). The controllable devices may be reverse blocking or reverse conducting and controlled by means of current, voltage or light. Non-bistable devices are assumed to be operated in the switched mode.
This Part is primarily intended to specify the basic requirements for converters in general and requirements applicable to line commutated converters for conversion of A.C. power to D.C. power or vice versa. The contents of this Part are also applicable to other types of electronic power converter provided that they do not have their own product standards.
These specific requirements are applicable to semiconductor power converters that either implement power conversion or use commutation (for example semiconductor self-commutated converters) or involve particular applications (for example semiconductor converters for A.C. motor drives) or include a combination of said characteristics (for example direct D.C. converters for electric rolling stock). This Part is applicable to all power converters not covered by a dedicated product standard, or if special features are not covered by the dedicated product standard. Dedicated product standards for power converters shall refer to this Part. NOTE 1: This Part is not intended to define EMC requirements. It covers all phenomena and therefore introduces references to dedicated standards which are applicable according to their scope.
NOTE 2: A large part of this Standard, particularly for power transformers, is covered in GB/T 3859.3 or GB/T 18494.1.
