3 TERMS AND DEFINITIONS

For the purposes of this document, the terms and definitions given in GB/T 19596 and GB/T 29259, as well as the following apply.

3.1
DC/DC converter
A device which can covert the electric energy of one DC voltage into the electric energy of another DC voltage
[Source: GB/T 19596-2017, 3.2.4.1, modified]
3.2
Overshoot and response time
Where any step change occurs to the input or output, the percentage of the maximum deviation of transient value from steady-state value in the steady-state value in the process from the moment when the controlled variable of DC/DC converter changes to when it is resumed to fall within the control error range is the overshoot; the response time is the time when the controlled variable reaches and remains within the permissible deviation range, starting from the moment when the input or output changes.
