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.
