power supply in english

The main limits of these power supplies reside in the low energy efficiency (typically less than 50%), which involves, in the case of high power handled, a significant development of heat, which must be disposed of to avoid damage to the equipment.
Classic is the redundant configuration with two identical devices[12] that control each other and replace each other in case of failure. On the contrary, the use of traditional power supplies with delegation of control and switching from external control units that could in turn fail is not very functional.
Also functional is the use of two power supplies that can be paralleled as long as both are able to safely support the entire load; in this case they would normally divide the power, extending the life of both, but at the same time in case of failure of one of the two, the service would be equally assured.
If there are no limits to safety, in practical applications we can also find power supplies with multiple equipment, classic avionics systems that in the military technical regime can reach even five[13].

The function of a linear voltage regulator is to convert a variable DC voltage into a constant, often specific, lower DC voltage. In addition, they often provide a current limiting function to protect the power supply and load from overcurrent (excessive, potentially destructive current).
Generally, programmable power supplies use a built-in microcomputer to control and monitor the operation of the power supply. Power supplies with a computer interface may use proprietary communication protocols or standard protocols and device control languages such as SCPI.
Power supplies often have protection against short circuits or overloads that could damage the power supply or cause a fire. Fuses and circuit breakers are two commonly used mechanisms for overload protection.
Both commercial and military avionics systems require a DC-DC or AC/DC power supply to convert power into usable voltage. These can often operate at 400 Hz in the interest of weight savings.
