But for a long time operating devices batteries could prove to be costly and complicated.
Unregulated dc power supply system with rectifiers and filters.
The diagram is shown below.
All low power system can be run with a battery.
It converts the utility voltage from a high voltage to a safe working voltage of your power supply.
If you need a power supply that can offer multiple dc output voltages then one regulated power supply with multiple outputs will be a better option than multiple supplies with single outputs.
Ac to dc is the most common type because electrical devices use direct current whereas the power supply from an outlet is in alternating current.
Lastly capacitor c1 is used to filter out the 50 60hz components present on the dc output.
Some called these power supply that ac adapter.
The power supply consists of transformer rectifier and filter circuits is called as unregulated or unstabilized power supply.
The best method used is in the form of an unregulated power supply a combination of a transformer rectifier and a filter.
Which now i will explain to you learn the unregulated power supply first.
Rectifier b1 converts the ac voltage to a dc voltage.
Unregulated power supply diagram.
You can use an unregulated power supply if it is matched closely to the voltage and current requirements of the device allowing it to still run smoothly.
Dc dc power supplies often convert power from a battery such as a car battery into the appropriate voltage for an electrical device.
For example digital circuits preamplifiers etc.

If you use other specific loads.
You need to use a regulated power supply.
But the output voltage across load resistor may be change due to change in load current and change in line voltage.
