Claim 7:
8. The testing system according to claim 7, wherein the current controller realizes one or two of the following controls:
according to a test current signal and the reference current signal output by the cascaded converter system parameter model, a control signal of the current generator is generated, and the testing current output by the current generator is adjusted by the control signal, and the testing current output by the current generator is identical to the reference current signal output by the cascaded converter system parameter model;
the current controller is configured to collect an output testing current ia of a single-phase current generator and a reference current ia.ref output by the cascaded converter system parameter model, calculate a current difference between the output test current ia and the reference current ia.ref, and transfer the current difference to a proportional-integral-resonant controller to generate a reference output voltage ua of the current generator, wherein the reference output voltage ua of the current generator is used to generate control signals of semiconductors in the current generator with a pulse-width modulation.
