Classification of switching power supply

People in the field of switching power supply technology is the development of related power electronic devices and the development of switching frequency conversion technology, the two parts promote each other to promote switching power supply every year to more than two digit growth rate toward the direction development of light, small, thin, low noise, high reliability and anti interference. Switching power supply can be divided into two major categories of AC/DC and DC/DC, DC/DC converter has been module type with the design technology and production technology at home and abroad and it has been mature and standardized and has been recognized by users. AC/DC modular, however, because of its own feature, in the process of modularization, makes the technique and technology problems of manufacturing more complicated . The structure and characteristics of the two types of switching power supply are described as follows.

2.1 DC/DC conversion

DC/DC conversion is the conversion of a fixed DC voltage into a variable DC voltage, also known as DC chopper. Chopper working mode has two ways, one is pulse width modulation mode, TS is unchanged and TON(general) is changed, the second is frequency modulation mode, TON is unchanged, Ts is changed (easy to produce interference). The specific circuit consists of the following categories:

(1) Buck circuit -- buck chopper, whose output average voltage

(2) Boost circuit - boost chopper, its output average voltage

(3) Buck-boost circuit -- Buck or Boost chopper, which

(4) CUK circuit - step-down or boost chopper, its output average electricity

The above is the non-isolation circuit, the isolation circuit has forward circuit, fly back circuit, half bridge circuit, full bridge circuit and push-pull circuit.

Today's soft switching technology makes DC/DC have a qualitative leap, VICOR designed and manufactured of a variety of ECI soft switching DC/DC converter, its maximum output power is 300W, 600W and 800W etc. The corresponding power density is (6.2,10,17)W/cm3, the efficiency is 80~90 %. Japan Nemic Lambda company's latest launched a high frequency switching power module RM series using soft switching technology with the switching frequency of (200 ~ 300)kHz, and power density has reached 27W/cm3, the use of synchronous rectifier (MOS and FET instead of SCHOT diodes) makes the efficiency of the entire circuit increased to 90%.

The overview of Switching power supply

Switching power supply is a device which use modern power electronics technology to control time ratio of switching tube open and off and maintain a stable output voltage of power supply, switching power supply is generally composed of IC and MOSFET which is controlled through pulse width modulation (PWM) compared with linear power. The cost of switching power supply increases with the increase of output power, but the growth rate is different. Linear power cost is higher than switching power supply at a certain output power point, which is called cost reversal point. With the development and innovation of power electronics technology and switching power supply technology constantly innovating, this cost reversal point is increasingly moving to low output power end, which provides a broad development space for switching power supply.

Switching power high-frequency is the direction of its development, high-frequency will make switching power miniaturization and make switching power into a wider range of applications, especially in the field of high-tech applications, promoting high-tech products miniaturization and portability. In addition, the development and application of switching power supply are of great significance in energy saving, resource saving and environmental protection.

The main power electronic devices used in switching power supply are diode, IGBT and MOSFET.

SCR has a small number of applications in switching power supply inputting rectifier circuit and soft start circuit, GTR is difficult to drive with low switching frequency and gradually replaced by IGBT and MOSFET.

Three conditions of switching power supply

1. Switching: power electronic devices work in the switching state rather than linear state

2. High frequency: power electronic devices work at high frequency rather than low frequency close to power frequency

3. DC: switching power supply output is DC rather than AC
