Title:
ACAC ALTERNATING-CURRENT POWER SUPPLY MODULE FOR RAILWAY SIGNAL POWER SUPPLY PANEL
Document Type and Number:
WIPO Patent Application WO/2023/272809
Kind Code:
A1
Abstract:
Disclosed in the present invention is an ACAC alternating-current power supply module for a railway signal power supply panel. The ACAC alternating-current power supply module comprises a PFC module, a DCDC module and an inverter module, wherein the PFC module is used for receiving a preset single-phase alternating-current input voltage input by an external single-phase alternating-current input power supply, and after performing boost processing on same, outputting a preset first direct-current voltage to the DCDC module; the DCDC module is connected to the PFC module, and is used for receiving the preset first direct-current voltage output by the PFC module, performing high-frequency isolation on the preset first direct-current voltage, so as to convert same into a preset second direct-current voltage, and then outputting the preset second direct-current voltage to the inverter module; and the inverter module is connected to the DCDC module, and is used for receiving the preset second direct-current voltage output by the DCDC module, and after performing inversion processing on same, outputting a preset single-phase alternating-current output voltage to the outside. The present invention can meet the requirements for a wide range of single-phase alternating voltage input, has high applicability, and can better meet the use requirement of a user, thereby improving the product usage experience of the user.
