Working principle
The DPD240040-P14N series AC/DC switching power supply adopts the principle of current conversion, which converts low voltage AC power into high voltage DC power. It is mainly composed of storage capacitors, rectifier diodes, thyristors, transformers, filter circuits, regulator circuits, electromagnetic interference suppression circuits and other components.The power supply is divided into two power modules, the pre-stage conversion module and the post-stage conversion module. The pre-stage conversion module is mainly composed of charged rectifier and intermediate filter. The charged rectifier diodes and capacitors form an alternating current looped circuit, and then the alternating current is changed into a direct current in the intermediate filter. The post-stage conversion module is mainly composed of a switching circuit, a transformer, a control circuit composed of a voltage regulator and various protective components. The working principle of the switch tube depends on the characteristics of the thyristor. The thyristor is controlled by the control circuit. Whenever the ON switch signal is switched, the thyristor will be activated, and the voltage will be discharged to the load through the transformer, The generated voltage is the required output voltage of the power supply.
