How to test the SMPS dynamic loading and acquire the maximum of Vpk+ and Vpk- (at worse case) from 50Hz ~ 10kHz?
Example: The PC power supply after R&D phase must be certified by DQC using the Electronic Load’s CC Dynamic mode to validate the worse case of transient response and voltage peak under the combination of loading level, frequency and duty condition. Using an Oscilloscope to capture Vpk+/- manually for 100 kinds of combinations is very time consuming, so the Dynamic Sweep function is built in for the new generation of Load. Simply setting the initial frequency, end frequency and step frequency can complete loading and measurement automatically. The maximum dot of occurrence frequency Vpk+ & Vpk- is displayed after execution.
