Abstract:

An on-board high-power DC / DC power converter (hereinafter referred to as the DC / DC) test scheme is introduced, using concept of V model and according to the semi physical simulation test method of DC / DC technology scheme of the digital simulation test, the DC / DC control circuit part of the rapid control prototyping simulation test, DC / DC power circuit of hardware in loop simulation test, the integrated power and control circuit DC / DC of the power hardware in the loop test and according to the results of the test and verify the iteration test. Through the semi physical verification test, the correctness of the design parameters and the performance index of the DC/DC are verified and tested, which ensure the reasonable and feasible of the DC/DC technical scheme.
