Modular power supply product classification:
1, green modular power
High-speed development of computer technology has led mankind into the information society, but also promote the rapid development of modular power supply technology. In the eighties, the computer fully adopted the switching power supply, the first to complete the computer power supply replacement. Then switching power supply technology has entered the field of electronic and electrical equipment. The development of computer technology, put forward the green computer and green module power supply. Green computer refers to environmentally friendly personal computers and related products.
2, high-frequency switching
The rapid development of the communications industry has greatly promoted the development of communications power supply. High-frequency miniaturized switching power supply and its technology has become the mainstream of modern communication power supply system. In the field of communications, the rectifier is usually referred to as the primary power supply, while the DC-DC converter is called the secondary power supply. The function of the primary power supply is to convert a single-phase or three-phase AC power grid into a DC power supply with a nominal value of 48V.
3, converter
DC/DC converter will be a fixed DC voltage into a variable DC voltage, this technology is widely used in trolley buses, subway trains, electric vehicles, stepless speed and control, and at the same time make the above control to obtain acceleration smooth, fast response performance, and at the same time receive the effect of saving power.
