This basic block diagram represents the essential components of a power supply unit, illustrating the process of converting electrical power from input to a stable output. It starts with the 'Transformers' that modify the voltage levels, followed by the 'Rectifier' that converts AC to DC power. The 'Filter' smooths out the ripples in the DC signal, and finally, the 'Regulator' ensures the output remains constant despite variations in input or load. This diagram serves as an educational tool for students and electronics enthusiasts to understand the fundamental workings of power supplies.
