The switching power supply consists of four parts:
1) main circuit: input from ac power grid to the main circuit of dc output.It mainly includes input filter, rectifier and filter, inverter, output rectifier and filter.
2) control circuit: on the one hand, from the output end of the sampling, by comparing with setting standards, then go to control inverter, change its frequency or pulse width, achieve output stability, on the other hand, according to the data provided by the test circuit, protect circuit differential, provide control circuit of the machine for all kinds of protection measures.Including the output end sampling circuit, feedback circuit and pulse width modulator.
3) detection and protection circuit: detection circuit has passed current detection, overvoltage detection, under-voltage detection, overheat detection, etc.Protective circuit can be divided into various types such as current protection, overvoltage protection, undervoltage protection, clamping protection, overheat protection, automatic restart, soft start and slow start.
4) other circuits: such as sawtooth wave generator, offset circuit, optical coupler and so on.
