    摘要: Provided is a cost-reduced DC-DC converter for an electric automobile. This DC-DC converter is interposed between an accumulation device and a drive motor of the electric automobile for raising the electric power of the accumulation device at the power driving time of the drive motor by using a reactor, a boosting switching element and a boosting diode, and for lowering a regenerative electric power at the regenerating time of the drive motor by using the reactor, a step-down switching element and a step-down diode. The boosting switching element has a higher current allowance than that of the step-down switching element.

    摘要: An inverter control device includes a DC power supply for outputting a first DC voltage, a voltage conversion unit for converting a voltage level of the DC voltage and supplying a first DC voltage to an inverter, a temperature detection unit for detecting an ambient temperature (element temperature) of the inverter, and a control device. The control device controls the voltage conversion unit such that the voltage VH lowers as the ambient temperature is lower, based on a temperature value representing a result of detection by a temperature sensor. A tolerable surge amount can thus sufficiently be ensured at a low temperature.
