Raspberry pi 5V 3A power supply with 3 ideas that you can do it.In many ways for using, it depends on the parts you have and other suitability. I will show you, a 12V to 5V converter step-down regulator. Digital DC Regulator If you are looking for a 5V power supply for the digital circuit.USB 5V to 1.5V /3V DC Adapter ( Converts USB to 1.5V or 3V output).

Many ideas of 12V and 5V Dual Power Suppl圜ircuit Diagram at 3A max 1.5V, 3V, 4.5V, 6V, 9V at 1.5A Selector Voltage regulator.12V 1A linear regulator using transistor and Zener diode.Other Linear Power supply Circuit Diagram Fixed Volts regulator: The table below compares various parameters of linear and switching forms. The difference between linear and switch-mode power supply Then, this DC voltage is converted back into an AC signal with a higher frequency than before.Īnd, the regulator circuit inside will produce DC voltage and current as desired. It does not contain a big-size transformer instead it directly converts the AC power into a DC voltage. How does the Switch-Mode Power Supply work The explanation above is oversimplified if you want in-depth information. Next, the voltage will go through the regulator circuit system to keep the voltage and current stable for a load. The AC voltage that goes through a power transformer will be raised or lower depending on the type of the transformer, and then converted to DC voltage. There are many kinds of power supply circuits. It is many useful but also can kill you! Safety first! Why should we use a linear power supply? Because it will save our money replacing our batteries when it is dead and convenient, no need to wait for sunlight when using a solar cell. We should use them instead of batteries and solar. We can adjust its output to various voltage and currents. They are more compact and easy to use than the battery. Often through an AC Adapter as a power supply. The AC line we currently used is the main source. For example, a battery charger inside a solar light, etc. But usually, we like to use it as a battery charger for a rechargeable battery. We can use the solar cell to power our circuit directly. Can be reused many times to save a lot of money. Rechargeable batteries are a better answer. Thus, they are the best uses for low current loads.īut for a heavier load, what should we do? The battery is small and easy to use anywhere. Let’s look at the three most used types of Power Supplies.Ī lot of circuits use a little power. GET UPDATE VIA EMAIL 3 Power Source for Electronic Devices
