Before we get into the difference between a regulated and unregulated power supply, let''s first start with understanding exactly what "power supply" even a set of similar devices. In most non-industrial settings, the available power, or
A regulated power supply has all the same parts that unregulated supplies do but with the addition of a voltage regulator. This part ensures the output is smooth and unchanging, regardless of draw or input. Delicate electronics require this
In the previous projects, the power source used was the AC mains. In this project, the solar energy will be tapped using a solar panel and it will be regulated to charge a 3.7 V battery. The 15 Watt solar panel used in

While a half wave rectifier is an option, its high power losses make a full wave rectifier or bridge rectifier a better choice for rectifying AC''s full cycle. The figure below shows a full wave bridge
