Abstract
The object of the present invention is to compensate for a difference in threshold voltage between a plurality of switching devices incorporated in a power module.The present invention solves the subject described above by mounting a switching device having a high threshold voltage in comparison with a different switching device at a location at which the temperature of the power module during operation is higher than that at another location at which the different switching device is mounted. Eventually, a power conversion apparatus of a high performance and a vehicle drive apparatus of a high performance can be provided.
