Tips

Ripple is an important parameter to mark the performance of DC power supply. Generally, manufacturers will provide technical data truthfully, which can be used as a comparative parameter. Users can also easily measure the ripple voltage of DC power supply by themselves through oscilloscope. It should be noted that the ripple of the same power supply is usually different under different loads. Generally, the measured ripple is under full load. In practical test and application, ripple is allowed to exist, as long as it meets the standard, but big enough. In fact, both linear power supply and switching power supply must have ripple, but the size is different. Through various means, it is only to restrain as much as possible and can not eliminate the ripple completely. The real zero ripple DC power supply can only be provided by the battery.
