Abstract

The invention discloses a converter. The converter comprises a rectifier module, an inversion module, an electric quantity detecting circuit and a control circuit, wherein the rectifier module is used for converting input first alternating current into first direct current and outputting the direct current, the inversion module is connected with the rectifier module and is used for converting the first direct current output by the rectifier module into second alternating current and outputting the second alternating current, the electric quantity detecting circuit is connected with the rectifier module and the inversion module and is used for detecting the electric quantity information of the rectifier module and the electric quantity information of the inversion module, and the control circuit is connected with the rectifier module, the inversion module and the electric quantity detecting circuit and is used for controlling the rectifier module according to a rectification signal generated by the received electric quantity information of the rectifier module and controlling the inversion module according to an inversion control signal generated by the electric quantity information of the inversion module. According to the converter, the integration level is high; due to the fact that the control circuit is integrated inside the converter and an extra control unit is not needed, the connection method is simplified, and the failure rate of the converter is reduced.

Description

technical field [0001] The invention relates to the technical field of power electronics, in particular to a converter. Background technique [0002] Converter power supply has the advantages of high efficiency, energy saving and low noise, so it is widely used in locomotive auxiliary power supply system. The converter is one of the core components of the auxiliary converter device. It contains many components and the interior space of the locomotive is small. This requires the converter to have the characteristics of compact structure and easy maintenance. [0003] The integration level of existing converters is not high, usually only the power device part is integrated. In this way, when the existing converter is installed in the converter cabinet for use, additional peripheral circuit devices need to be configured, resulting in an excessively large volume of the converter cabinet and inconvenient maintenance. [0004] Based on the above situation, there is an urgent nee...
