Power supply is a crucial element of any electrical and electronic system which is used to give electrical supply to electrical loads. The primary purpose is to alter the electrical current from source to the specific voltage, frequency and current to supply the load.
Are batteries regulated or unregulated?
Power supply is an electrical circuit that provides power to another electrical device. There are several types of power supplies, but the regulated power supply (RPS) and unregulated power supply (URPS) are the leading ones, based on the types of output.
Regulated and unregulated powers supplies are commonly referred to as DC power supplies, but even though there is also AC power supplies in use. Batteries, on the other hand, are unregulated power supplies because their output voltage varies with charging and loading state.
The main difference between regulated and unregulated power supply is:
