Scope

This part of GB/T 14860 specifies the method for preparing detailed specifications for switching power supply transformers released according to the capability approval procedure specified in GB/T 14860.1-2012. This part includes a blank detailed specification (BDS), which specifies the format and indicates the tests suitable for such components; while the tests ultimately selected for inclusion in the inspection checklist are determined by the writers of the specification. This specification also stipulates the corresponding rated values and characteristics.
The components specified in this part are used in conjunction with semiconductor devices operating in a switching state to transmit power, with the input waveform being either sinusoidal or non-sinusoidal, symmetrical or asymmetrical.
