POWER SUPPLY
Power supply is a reference to a source of electrical power. A device or system that supplies electrical or other types of energy to an output load or group of loads is called a power supply unit or PSU. The term is most commonly applied to electrical energy supplies, less often to mechanical ones, and rarely to others.
Power supply types
Power supplies for electronic devices can be broadly divided into linear and switching power supplies. The linear supply is a relatively simple design that becomes increasingly bulky and heavy for high current devices; voltage regulation in a linear supply can result in low efficiency. A switched-mode supply of the same rating as a linear supply will be smaller, is usually more efficient, but will be more complex.
Circuit Breakers
One benefit of using a circuit breaker as opposed to a fuse is that it can simply be reset instead of having to constantly replace the blown fuse. A circuit breaker works once an overloaded current causes some element to heat and trigger a spring which shuts the circuit down. Once the element cools, and the problem is identified the breaker can be reset and the power restored.
Power conversion
The term "power supply" is sometimes restricted to those devices that convert some other form of energy into electricity (such as solar power and fuel cells and generators). A more accurate term for devices that convert one form of electric power into another form (such as transformers and linear regulators) is power converter. The most common conversion is AC-DC. This is a conversion from the household current AC, to the direct current that is used in your car, and most electronics.
Fuses
A piece of wire is connected between two metal ends. The two metal ends of the fuse are connected by either a tube of glass or plastic which surrounds the wire. If too much current flows, the wire overheats and melts. This interrupts the power supply, and the equipment stops working until the problem that caused the overload is identified and the fuse is replaced.
There are two types of fuses, slow-blow and fast-blow. In a fast-blow fuse, the wire inside the fuse will melt if the current exceeds the rated current, even if it is just for a fraction of second. This concise process is important in electronic equipment where even a small spike in the current could damage the equipment. A slow-blow fuse is designed to only melt when there is a continuous overload. Slow-blow fuses are ideal for motor systems.
