  • Patent number: 9048722
    Abstract: The present application discloses a current equalizing busbar for a converter comprising: a direct current busbar connected to a DC terminal of the converter and positive terminals and negative terminals of respective power modules; and an alternate current busbar connected to AC terminals of the respective power modules and a load; wherein, when the converter operates, a sum of an inductance caused by the DC busbar between the DC terminal and a positive terminal or a negative terminal of a power module and an inductance caused by the AC busbar between the load and an AC terminal of the power module is equal to a sum of an inductance caused by the DC busbar between the DC terminal and positive terminals or negative terminals of other power modules and an inductance caused by the AC busbar between the load and AC terminals of said other power modules.
