Analog Power Supply 50V/50A (28V/85A)

This project showcases a custom-built analog power supply unit capable of dual-mode operation: 50V/50A or 28V/85A when powered by 220V AC input. The design employs pure analog signal processing for core functionality. A PIC18F2420 microcontroller serves auxiliary functions only, handling parameter display and configurable overload protection settings.
