This process is repeated for each cycle and thus the repel is reduced across the load. It is shown in the above Figure.
The Importance of Filtering for Power Supplies
To prevent propagating noise to other equipment that is connected to the AC (power) line, an Electromagnetic Interference (EMI) filter is placed between the AC line and the rectifier in the SMPS. The capacitors filter the power line, decoupling it from any common-mode noise that may be generated by the SMPS, and suppress EMI.
