What are the common power supplies?

Voltage regulating power supply is called rectifier power supply, which converts alternating current into direct current through transformer and rectifier. The purpose is to convert other forms of energy into electric energy, which is characterized by adjustable voltage.

2, switching power supply

Switching power supply, also known as switching power supply and switching converter, is a high-frequency power conversion device and a kind of power supply. Its function is to convert a level of voltage into the voltage or current required by the client through different forms of architecture.

The input of switching power supply is mostly AC power supply or DC power supply, and the output is mostly equipment that needs DC power supply. Switching power supply converts voltage and current between them.

3. Inverter power supply

Inverter uses thyristor circuit to convert direct current into alternating current, which corresponds to the reverse process of rectification and is defined as inverter.

Inverter power supply is widely used in various fields: electric power, communication, industrial equipment, satellite communication equipment, military vehicles, medical ambulances, police cars, ships, solar energy and wind power generation.

4. Variable frequency power supply

Variable frequency power supply converts alternating current in commercial power into pure sine wave through AC, DC and AC, and the output frequency and voltage can be adjusted within a certain range. Frequency conversion power supply is a frequency conversion device composed of the whole circuit, which has been widely used.

5. Uninterruptible power supply

Uninterruptible power supply (UPS) is a system equipment that connects the storage battery with the host and converts DC power into commercial power through module circuits such as host inverter. It is mainly used to provide stable and uninterrupted power supply for a single computer, computer network system, electromagnetic valve, pressure transmitter and other power electronic equipment.
