An electronic device needs to use a power. We have a lot of power supply circuit. We recommend the example tag: (It may make you find the circuit easier.)Fixed voltage regulator :: 3-volts :: 5-volts :: 6-volts :: 9-volts :: 12-volts :: 15-volts :: Protection :: Transformerless :: Negative Power Supplies :: Dual output power supply :: Variable DC Power Supply :: 0-30V DC Power SupplyAdjustable DC power supplies :: Switching power supply :: High current :: High voltage :: Zener Diode Regulators :: Multi voltage regulated :: 7805 Regulator Circuits :: LM317 Circuits :: PC power supply circuits
and We love renewable energy, clean, and long with solar.
Note: If you do not see the power supply circuit that you need. Please use the search box below!
To increase current transformer on the power supply. To save money with this idea, just only change connecting of on original transformer windings.
Small Zener diode voltage regulator circuit with PCB, using transistor and few parts. it is simple and cheap fixed dc source circuit. As one of best choice.
Transistor Variable power supply 1A, 0-30V project with PCB. Using transistor boost current to 1A. No IC. No Zener diode. But steady voltage.
This is LM317 voltage selector power supply projects can select output 1.5V,3V,4.5V,5V,6V,9V at 1.5A current. you can use as as battery, so saving.
If you need a dual power supply. But you only have a single supply source. So should build this power supply splitter circuit.
