High Current Variable Voltage Regulator 2-36V 10A
The high current power supply circuit is designed to provide a stable output of up to 10A, which is suitable for various applications requiring significant current. The adjustable voltage feature allows users to set the output voltage within a range of 2V to 36V, making it versatile for different electronic projects.
The circuit typically comprises a transformer, rectifier, and voltage regulator. The transformer steps down the AC mains voltage to a lower AC voltage suitable for the rectification process. A bridge rectifier converts the AC voltage to DC voltage, which is then filtered using capacitors to smooth out the ripple, resulting in a stable DC output.
The core of the adjustable voltage functionality is often achieved through the use of a variable voltage regulator, such as the LM317 or a similar device. This regulator allows for fine-tuning of the output voltage by adjusting a pair of resistors connected to the adjustment pin of the regulator.
To handle high currents safely, the circuit may include heat sinks to dissipate excess heat generated during operation, ensuring the components operate within their safe temperature ranges. Additionally, fuses or circuit breakers can be integrated for overcurrent protection, safeguarding both the power supply and connected devices.
Overall, this power supply circuit is ideal for hobbyists and professionals alike, providing reliable performance for a wide range of electronic applications requiring adjustable voltage and high current capabilities.Yesterday I no enhance the circuit in my blog.
