High Current Adjustable Power Supply Circuit using LM317

High current variable power supply circuit

Variable power supplies are available in different ranges but they provide very low current of one or two amperes, they can’t drive high power devices like motor or high power lamps.So to get through such problems I introduce a high current variable voltage power supply circuit which can drive 10A of load, the current handling…

Variable Power Supply circuit

Variable voltage power supply is essential for any electronic hobbyist to begin their electronics lessons. For different applications you may need different voltages. So it becomes impossible to use multiple fixed power supplies all the time.Also this variable power supply circuit ensures the protection of other circuit parts from voltage fluctuations. So in this article…
