What are the types of power supplies?

Communication power supply: in essence, it is a DC/DC converter type power supply, but it is generally powered by DC-48V or -24V, and the backup battery is used as a backup of DC power supply, and the DC power supply voltage is converted into the working voltage of the circuit.

Led Driver power supply: constant current output, used to control the brightness of the LED lamp constant.

Battery charger: such as three-stage constant current constant voltage battery charger, charging power supply for charging supercapacitors, etc.

Emergency power: Integrate battery chargers, batteries, inverters, or DC/DC regulators and other circuits for temporary use in the event of a mains power outage.

Special power supply: the technical specifications of the power supply are different from the commonly used power supply, which is mainly that the output voltage is particularly high, the output current is particularly large, or the stability, dynamic response and ripple requirements are particularly high, or the voltage or current of the power output is pulsed or some other requirements. This makes the design and production of such power supplies have more special and even more stringent requirements than ordinary power supplies. For example: high voltage and small current power supply, high current power supply, 400Hz input AC/DC power supply, pulse power supply, intrinsically safe power supply, explosion-proof power supply, safe power supply (a low signal leakage power supply), etc
