The circuit is a 5V 1 ampere power supply, which is suitable for mobile phone charger’s, microcontroller power supply, audio video players, portable amplifiers, small DC motors, LED light circuits and Bluetooth/Wi-Fi modules.
What are the various Parts Of Power Supply Boards And Their Functions?
There are various components to basic power supplies. These parts assist the device in stepping up or down voltage, converting power, and reducing ripple voltages, which are lingering changes in voltage that waste energy and cause overheating.
- Transformer: This device converts the input voltage to the required exiting voltage level. The voltage may be stepped up or lowered by these devices. Usually, the required DC voltage is considerably lower than the incoming AC voltage from the main power source.
- Rectifier: The power supply uses a rectifier, which could be a half-wave, full-wave, or bridge device, to change the incoming power from AC to DC.
- Filter: When AC power is converted to DC, the waves still have identifiable peaks that need to be eliminated. Although the waves are not fully eliminated by the filter, they are greatly diminished. This component produces unregulated electricity as its output.
- Regulator: A voltage regulator eliminates any voltage spikes or drops that can harm connected devices by reducing the ripple voltages the filter leaves behind.
The specific function of the power supply unit depends on the power supply components. Because of this, not all power supply will have the same components. It is also necessary to use high quality components from makers like Mornsun, available on Campus Component for efficient operations.
What Are Electric Components Required To Build A Cost-Effective Power Supply Board?
Electronic components required-
- The ATX power supply, which you can buy used or take from an old computer (most of them still function), delivers all the fundamental voltages that we'll need: 3.3V, 5V +12V.
- Booster DC-DC 100W, 6A (5V Into 35V out) (You are welcome to use a better one; that was the best I could locate close by.)
- XL6009 DC-DC Booster, 4A (3V in to 35V out)
- Female USB ports two (or just use one from old devices as I did)
- ON/OFF Switch
- six red banana connectors and six black banana connectors
- Three potentiometers, each with a 50 Kohm cap.
- 220-ohm resistor with a green LED
- Voltmeter and Ammeter, 2x DC 100V
