The invention discloses a rectification module of an intelligent high frequency switch power supply. A main controller is connected with a DC/DC (Direct Current/Direct Current) transfer circuit, an overvoltage overcurrent and short circuit protection circuit, an overtemperature protection circuit, a communication interface circuit, and an information acquisition and feedback circuit; the input terminal of the DC/DC transfer circuit is sequentially connected with a passive PFC (Positive feedback circuit) correction circuit, a rectification circuit, and a over-lightning protection processing and filter circuit; the output terminal of the DC/DC transfer circuit is sequentially connected with a smoothed filter circuit and an output protection circuit; the whole connection forms a rectification module. The rectification module is an important part of the intelligent high frequency switch power supply, and integrates the rectification function with the charging function to effectively play the rectification role, thus the direct current voltage output and the operating voltage output of the switch power supply are ensured stably.
