How to measure the output ripple of a switching power supply using an oscilloscope?

Article Source：Kinri Energy | Author：Kinri Energy | Issuing Time：2024.06.11
An oscilloscope is an instrument used to measure electronic signals and can be used to measure the output ripple of a switching power supply. The following are the steps to measure the output ripple of a switching power supply using an oscilloscope:



1. Prepare the oscilloscope and test probe

Firstly, it is necessary to prepare an oscilloscope, a test probe, and relevant connecting wires. The testing probe should be selected with sufficient bandwidth and sensitivity to measure the output ripple of the switching power supply.

2. Connect the oscilloscope and test probe

Connect the oscilloscope and test probe through connecting wires and ensure that the input impedance of the probe matches the input impedance of the oscilloscope. It is also necessary to correctly connect the probe to the output terminal of the tested switch power supply.

3. Set oscilloscope parameters

Turn on the oscilloscope and select the appropriate measurement mode (such as AC coupling, DC coupling, etc.). Then, it is necessary to set parameters such as vertical gain, horizontal time base, and trigger conditions in order to output accurate ground wave capture. Capturing switch power supply

4. Start measuring

After setting the oscilloscope parameters, the measurement head can be started. Connect to the output terminal of the tested switch power supply and adjust the vertical gain and horizontal time base of the oscilloscope so that the output ripple can be clearly seen.

5. Analyze measurement results

After capturing the output ripple, the waveform can be analyzed as an example. It can calculate parameters such as peak to peak value, frequency, and amplitude of the ripple. These parameters can be used to evaluate the performance and quality of switching power supplies.

It should be noted that the generation of output ripple in switching power supplies is related to the switching action of the switching tube, so it is necessary to choose an oscilloscope and probe with sufficient bandwidth for measurement. In addition, safety precautions should be taken during measurement to avoid electric shock or damage to the equipment.
