Adjustable High voltage power supply
The Adjustable High Voltage Power Supply circuit is designed to deliver precise voltage outputs, essential for various applications requiring high voltage levels. The input stage utilizes a transformer to step down the mains voltage to a manageable level, typically 12V AC, which is then rectified by a diode bridge to produce a DC voltage suitable for further processing. The diode bridge must be rated for at least 1A to ensure reliability under load conditions.
The operational amplifier MC1741 plays a crucial role in enhancing the circuit's capability to regulate higher voltages. By integrating this op-amp, the circuit can achieve more precise voltage adjustments, which is vital for applications that demand accuracy. The adjustable voltage regulator IC 78L05 is employed to maintain a stable output voltage of 20V DC, with a maximum current output of 3A, ensuring that the power supply can meet the demands of connected loads without significant voltage drop or instability.
The design also incorporates the LM317L IC, a well-regarded three-terminal adjustable voltage regulator, which allows for output voltage adjustments between 8V and 160V, depending on the application requirements. This regulator is particularly useful in applications where a wide range of output voltages is necessary. The LM723 IC further enhances the circuit's versatility, providing a regulated output voltage between 2V and 37V at a lower current output of 150mA, suitable for less demanding applications.
In summary, this circuit design offers a comprehensive solution for generating adjustable high voltages, utilizing a combination of rectification, regulation, and amplification to achieve stable and precise output voltages. The careful selection of components ensures that the circuit can handle various loads while maintaining performance, making it suitable for a wide range of electronic applications.The schematic diagram come from circuit: Adjustable High Voltage Power Supply 0 to 1000V power supply.
