The four stages of a power supply are: (1) **Transformation**, where the input voltage is adjusted using a transformer; (2) **Rectification**, which converts AC to DC using diodes; (3) **Filtering**, where capacitors smooth out the DC signal; and (4) **Regulation**, which maintains a constant output voltage using voltage regulators. Each stage ensures the power supply delivers safe and steady DC power to electronic devices.
