Description

technical field [0001] The invention relates to an inverter device and a vehicle. Background technique [0002] In recent years, there has been an increasing demand for higher motor efficiency and higher output. In order to achieve high efficiency and high output of the motor, it is necessary to flow a high current and to perform control to optimize the timing. In the case of driving the motor with such a high current, the influence of heat generated by the motor and elements related to its driving cannot be ignored. In particular, since the components related to the drive of the motor include an inverter device including a switching element with a large heat generation, it is important to efficiently cool them. [0003] On the other hand, Patent Document 1 discloses a technology for improving the efficiency of a cooling pump by focusing on cooling only necessary equipment according to the operation mode of a motor vehicle. [0004] prior art literature [0005] patent d...
