Abstract

The invention relates to a method for building an industrial AC/DC wide range input power module, which comprises the following steps: connecting an AC input and a DC input to the input end of a bridge circuit first, wherein the input end and the output end of an AC input high-frequency transformer are connected with the output end of the bridge circuit and the input end of a DC input channel respectively. The method is characterized is characterized in that the input end of a DC input high-frequency transformer is connected with the output end of the bridge circuit through an input switch, so that the bridge circuit forms two paths of outputs; and two ends of a switch controller with the switch and the output end of the bridge circuit are respectively for driving the switch, and simultaneously, the enable end and the power supply end of the switch controller are respectively connected with the AC input high-frequency transformer. The method has the advantages that the alternating current and the direct current share an interface input, have no polar requirement after rectification by a rectifier bridge and reduce the complexity of user wiring, the power supply conversion efficiency is improved, and the system loss is reduced. The wide range voltage input capacity enhances the system application level.

Description

technical field [0001] The invention relates to a method for building an industrial AC-DC wide-range input power supply module, which adopts a common interface AC-DC non-polarity wide-range input power supply. Background technique [0002] Common AC and DC wide-range input power supplies have the following two architectures: [0003] Such as figure 1 As shown, the AC and DC adopt dual independent inputs: one is the AC input which is output after passing through the rectifier bridge and the isolation converter, and the DC input is directly connected in parallel to the output channel through another interface through a diode. The method has a simple architecture and does not require channel control. However, a connector needs to be added, and there is a polarity requirement for the input. [0004] Such as figure 2 As shown, the AC and DC shared input interface: the interface adopts three-pin input, and the AC and DC input must strictly follow the definition of the input p...
