As the title says, the ACDC switching power supply outputs 5V voltage through LDO. How to filter it next?Below is the schematic diagram I used and the waveform collected by the oscilloscope.
Resources used in practice
4 rectifier diodes, 500R resistor (as load), oscilloscope, signal source
Note: The resistance value does not need to be accurate. This resistor is used as a load. The resist
When using a three-phase AC motor, it is necessary to know the phase sequence of the connected three-phase power supply. If the phase sequence is incorrect, the rotation direction of the motor will be
