一种驱动装置,具备:马达;蓄电装置;第1升压变换器,其在蓄电装置侧与马达侧之间随着电压的变换来交换电力;第2升压变换器,其与第1升压变换器并联连接,并且在蓄电装置侧与马达侧之间随着电压的变换来交换电力;电子控制单元,其对第1升压变换器和第2升压变换器进行控制。电子控制单元,在要向蓄电装置输入的来自马达侧的电力为比蓄电装置的输入限制大的过大电力输入时,对第1升压变换器和第2升压变换器进行控制,以使得第1升压变换器以及第2升压变换器中的损失并非最小。
A driving device includes a motor; a power storage device; a first boost converter configured to exchange power by voltage conversion between a power storage device side and a motor side; a second boost converter connected to the first boost converter in parallel and configured to exchange power by voltage conversion between the power storage device side and the motor side; and an electronic control unit configured to control the first boost converter and the second boost converter. The electronic control unit controls the first boost converter and the second boost converter such that the loss of each of the first boost converter and the second boost converter is not minimized during an excessive power input in which power to be input to the power storage device from the motor side is greater than an input limit of the power storage device.
