The role of electrolytic capacitors in switching power supplies are:
1. Blocking DC: The function is to prevent the passage of DC and allow the passage of AC.
2. Bypass (decoupling): Provide a low impedance path for some parallel components in the AC circuit.
3. Coupling: As a connection between two circuits, it allows AC signals to pass through and be transmitted to the next-level circuit.
4. Filtering: Change the rectified sawtooth wave into a smooth pulsating wave, close to DC.
5. Energy storage: store electrical energy and release it when necessary.
