Power Supply Circuits

DC Voltage Doubler Circuit is like small power booster. It takes normal battery power and make almost double. It use smart parts like diodes and capacitors and they work like tiny switch and small electric bucket. Sometimes many also use transistor or tiny chip to help. Imagine electric flow from battery like small stream. This […]

This Simple Regulated Adjustable Power Supply Circuit using IC 723 show how to make one simple power supply circuit. It can change voltage up and down. We can use one chip call LM723 with some people say IC 723. This chip is good and it take power from plug and makes it stable. Also we […]

This High Current IC 7805 Voltage Regulator Power Supply Circuit tell how to make one circuit for strong power supply using one chip name LM7805. This chip take high voltage and give out stable 5V power for devices. But normal LM7805 give only small current which is not enough for big device. In this circuit […]

This article for 6V to 12V Converter Circuit (High Current) show how to make a helper circuit. It takes 6V battery and give 12V power. If we have motor or toy which needs 12V then this circuit can help make it work. Thing that need more power can use this circuit which gives more current […]

This article for Stabilized Adjustable Power Supply 0-15V/5A Circuit tell us about how to make special power supply circuit. It can give voltage from 0 to 15V. Also it can run many electric devices because it give 5 amp current. One more good thing is this power supply stays stable. Voltage does not changes much […]
