The Analog Linear Power Supply project focuses on designing a 10V linear power supply capable of delivering up to 10A of current. The project involves multiple stages, including step-down transformation, full-wave rectification, smoothing, voltage regulation, and current limiting. The design also incorporates protection mechanisms for overload and short circuit conditions.
The Analog Linear Power Supply project aims to provide a reliable and stable voltage and current output for high-power loads. This is achieved through a multi-stage process that involves transforming the input voltage, rectification, voltage smoothing, regulation, and current limiting. The project addresses challenges associated with handling high current while minimizing current error.
The methodology of the project involves the following key stages:
-
Step Down Transformer: A step-down transformer is used to reduce the 230V input voltage to a more manageable level.
-
Full-Wave Rectification: The GBPC3506W Bridge rectifier is used to rectify the voltage, converting it into pulsating DC.
-
Smoothing Stage: A 10mF capacitor is employed to smooth the rectified output, reducing voltage ripples.
-
Regulating Stage: The regulated voltage is achieved using two transistors (MJ4502 and BC547A as Sziklai pair), a 10V Zener diode, a 150Ω resistor, and a diode.
-
Current Limiting Stage: The circuit incorporates a current limiting mechanism to restrict the maximum current output to 10A.
The PCB design is optimized for the specific requirements of the Analog Linear Power Supply. The layout ensures proper heat dissipation through the use of a heat sink with the MJ4502 transistor and the bridge rectifier.
