the diagnosis result being correct and being represented by Fcheck=1 when at least one value of three diagnosis variables ΔVAB(k), ΔVBC(k), and ΔVCA(k) is greater than a threshold TH(k) at a certain time during a preset current cycle after completing the fault diagnosis; and conversely, the diagnosis result being wrong and being represented by Fcheck=0 when values of all sampling points of ΔVAB(k), ΔVBC(k), and ΔVCA(k) all do not exceed the threshold TH(k) during the preset current cycle after completing the fault diagnosis, where the threshold TH(k) is set to VDC(k)/2+V.
