Generally, such modules are called load (POL) power supply systems or point-of-use power supply systems (PUPS). Because of the advantages of modular structure, it is widely used in switching equipment, access equipment, mobile communication, microwave communication, optical transmission, router and other communication fields, automotive electronics, aerospace and so on.
Especially in recent years, due to the rapid development of data service and the continuous promotion of distributed power supply system, the increase of module power supply has exceeded the primary power supply. Module power supply has the function of isolation, strong anti-interference ability, own protection function, easy to integrate. With the extensive use of semiconductor technology, packaging technology and high-frequency soft switch, the power density of modular power supply is increasing, the conversion efficiency is increasing, and the application is becoming simpler.
People in the field of switching power supply technology is to develop related power electronic devices, while developing switching frequency conversion technology, the two promote each other to promote the switching power supply to light, small, thin, low noise, high reliability, anti-interference direction with more than two digit growth rate every year. Switching power supply can be divided into AC/DC and DC/DC two categories, DC/DC converter has realized modularization, and the design technology and production process at home and abroad have been mature and standardized, and has been recognized by users, but the modularization of AC/DC, because of its own characteristics in the process of modularization, encounter more complex technology and process manufacturing problems. The structure and characteristics of the two types of switching power supply are described below

DC/DC conversion is the conversion of a variable DC voltage into a fixed DC voltage, also known as DC chopper. Chopper working mode has two, one is the pulse width modulation mode Ts unchanged, change ton(universal), the other is frequency modulation (
(1) Buck circuit – buck chopper, the output average voltage U0 is less than the input voltage Ui, the polarity is the same.
(2) Boost circuit — boost chopper, the output average voltage U0 is greater than the input voltage Ui, the polarity is the same.
(3) Buck-boost circuit — Buck or Boost chopper, whose output average voltage U0 is greater than or less than the input voltage Ui, polarity is opposite, inductive transmission.
(4) Cuk circuit – buck or boost chopper, the output average voltage U0 is greater than or less than the input voltage Ui, the polarity is opposite, capacitor transmission. There are Sepic and Zeta circuits.
The above is a non-isolated DC-DC converter circuit. The isolated DC-DC converter includes forward circuit, flyback circuit, half-bridge circuit, full-bridge circuit and push-pull circuit.
Today’s soft switching technology has made a qualitative leap in DC/DC. VICOR has designed and manufactured a variety of ECI soft switching DC/DC converters, whose maximum output power is 300W, 600W, 800W, etc. The corresponding power density is (6.2, 10, 17)W/cm3, and the efficiency is (80 ~ 90) %. The RM series of high frequency switching power module, which adopts soft switching technology, launched by TDK-Lambda in Japan, has a switching frequency of (200 ~ 300)kHz and a power density of 27W/cm3. By using synchronous rectifier (MOSFET instead of Schottky diode), the efficiency of the whole circuit is improved to 90%.
