Power Supply Circuit Board
Description
A Power Supply Circuit Board is the unsung hero within electronic devices. It's a specialized circuit board designed to convert and regulate the incoming power source (usually AC) into a suitable form of power (usually DC) that the device's components can use. Think of it as the device's power transformer and stabilizer all in one!
Key Components and Their Roles:
1. Transformer: This component steps down the incoming AC voltage to a lower level, making it safer for the subsequent stages.
2. Rectifier: It converts the alternating current (AC) into a pulsating direct current (DC).
3. Capacitor: This smooths out the pulsating DC, filtering out the AC component and providing a steadier DC output.
4. Voltage Regulator: This circuit ensures the output voltage remains stable, even if the input voltage or load changes.
