Power Supply Design: Load Step Response with a SIGLENT DC Electronic Load

 April 3, 2020

In this video, I compare the response from two power supplies using a stepped load to show the differences between a well-tuned supply and one that exhibits excessive ringing. Also, add in some basic instrument requirements to help get you started making your own step load tests.

Here, I use a SIGLENT SDL1X-E DC Electronic load to perform the dynamic load requirements, an SPD1168X power supply to power the board, a CP4070 current probe to monitor the load current, and a SIGLENT SDS2354X Plus oscilloscope to measure the response and perform some averaging to clean up noise.
