The traction rectifier is composed of a rectifier transformer and a rectifier. The main function: the AC incoming line voltage is stepped down by the rectifier transformer, and then the AC power is converted into the DC traction motor of the DC power supply vehicle through the rectifier;
In order to improve the power quality of the direct current and reduce the pulsation (fluctuation) of the direct current power supply, a multi-phase rectification method is generally adopted, which may be six-phase, twelve-phase rectification or twenty-four-phase rectification
The rectifier transformer not only acts as a step-down, but also turns the three-phase alternating current into a multi-phase alternating current for rectifier rectification.
