The SEG series module is a high-performance DC charging module. Its main function is to rectify the three-phase AC input from the power grid into a DC output, providing a fast DC charging current for electric vehicle batteries. It can also be used to provide stable voltage and current for equipment. Including 30KW100A1000V and 40KW133A.
The internal circuit of the module is mainly divided into two parts.
The first part is responsible for rectifying the wide-range three-phase AC input voltage into an internal high-voltage bus, and completing the correction of indicators such as PF and THD.
The second part is responsible for converting, isolating, and rectifying the internal high-voltage bus, and outputting the corresponding DC voltage/current based on different monitoring settings.
