Make a principal diagram for SMPS

Question

Accepted Answer

A principal diagram for SMPS is a schematic representation of the components and connections in a Switched Mode Power Supply.

The diagram should include the input and output connections, the transformer, the rectifier, the filter capacitor, the switching transistor, and the feedback circuit.
The input voltage is rectified and filtered to provide a DC voltage that is switched on and off by the transistor to produce a high-frequency AC voltage.
This AC voltage is then stepped down by the transformer and rectified again to produce the final output voltage.
The feedback circuit monitors the output voltage and adjusts the switching frequency to maintain a constant output voltage.
Examples of SMPS include laptop chargers, LED drivers, and power supplies for electronic devices.
