Electric vehicle DC-DC converter test

The internal electrical circuit of an electric vehicle is a complex systematic project, in which key components must be specially adapted to electric vehicles. Take the DC-DC converter of an electric vehicle as an example. It is an extension of the traditional switching power supply technology and has developed into a dedicated DC-DC converter for electric vehicles. The difference between them is that the input voltage, current and power of the dedicated DC-DC converter for electric vehicles are larger.

NGI's high-power DC power supply can meet the user's various voltage level tests. With high-power DC electronic loads and NXI architecture measurement and control boards, the overall test system can simulate various working states of electric vehicle DC-DC converters. This test system can be applied to the DC-DC converter test of electric vehicles and the DC-DC converter test of fuel cell vehicles, and can be adapted to the test of DC-DC converters of various specifications such as 3.3kW and 6.6kW.
