Abstract

The invention provides a boost regulator, which comprises a commercial power input interface, an isolation transformer, a rectifier and filter circuit, a DC/DC converter, a constant-current and constant-voltage charging circuit, a storage battery, a switching circuit and a power output interface, wherein the commercial power input interface is electrically connected with an input end of the isolation transformer; an output end of the isolation transformer is electrically connected with the input end of the rectifier and filter circuit; the output end of the rectifier and filter circuit is divided into two paths, one path is charged by the storage battery through the constant-current and constant-voltage charging circuit, the output end of the storage battery is electrically connected with an input selection end of the switching circuit and the other path is electrically connected with the other input selection end of the switching circuit through the DC/DC converter; and the output end of the switching circuit is electrically connected with the power output interface. Through two paths of selection output of the DC/DC converter and the storage battery, stable output of DC voltage at a commercial power supply stage is ensured and stable output of the DC voltage achieved by the storage battery as a stand-by power supply method is also ensured.

Description

technical field [0001] The invention belongs to the technical field of boosting and stabilizing devices, in particular to a boosting and stabilizing device. Background technique [0002] In the railway system, the electrical equipment generally converts the AC mains power into DC power with stable voltage through the booster voltage regulator device at the mains interface to ensure the stability of the power supply voltage and the operation of the electrical equipment. Generally, the booster voltage regulator device The power output interface of the system is fixed, and the connection relationship between the power output interface and the electrical equipment can only be adjusted by adjusting the height of the booster voltage regulator device or using the lifting of the transmission line, which makes the cabinet body of the booster voltage regulator device can be lifted or lowered. It makes the power supply line complicated and increases the daily work of maintenance person...
