The design of variable pressure filter circuits, rectifier circuit, voltage circuit, adjustable circuit and protect circuit for most. This LM317 used LM337 and L7812, and to realize the power circuit regulator 4013. This article altogether divides into four chapters, the first chapter directs to say narrates the constant voltage directcurrent power supply in daily life importance, this graduation project second chapter adjustable cocurrent voltagestabilized source performance index, introduced the cocurrent voltagestabilized source each performance third chapter adjustable cocurrent voltagestabilized source principle, summarized its each part of principle of fourth chapter adjustable cocurrent voltagestabilized source design and the manufacture, mainly introduced this design main primary device and the content contains this design the electric circuit schematic diagram and carries on this design end product examines and confirms its performance.
