    摘要： The present improvement essentially integrates a DC link inductance within an interphase power transformer (IPT). The integration is achieved by creating auxiliary magnetic paths for leakage inductance inside the IPT core 50. The magnetic path can be created, for example, by incorporating extra portions of magnetic material commonly referred to hereinafter as shunts 100. The IPT flux shared between windings 60 does not cross these shunts. Therefore, this magnetic path increases the self-inductance of the IPT but does not contribute to the mutual inductance between windings. This extra magnetic path allows for leakage inductance of a much higher quantity than that achievable with a conventional IPT.
