    Abstract: A voltage command value of a converter is set by executing the step (S100 to S140) of determining a candidate voltage of a system voltage VH as a converter output voltage in a voltage range from the minimum necessary voltage (VHmin) corresponding to induction voltage of a motor generator (MG11, MG2) and a maximum output voltage (VHmax) of the converter; the step (S150 to S165) of estimating power loss at the battery, converter, inverter and motor generator, at each candidate voltage, and calculating total sum of estimated power loss of the overall system; and the step (S170 to S190) of setting the voltage command value VH# based on the candidate voltage that minimizes the total sum of estimated power losses among the candidate voltages.

    Abstract: A power conversion device has an internal power supply switch configured of an n-channel MOSFET and a bias power supply switch connected in parallel with the internal power supply switch, wherein, when an output voltage of an internal power supply circuit is equal to or greater than a predetermined value when a power supply is started up, the bias power supply switch opens a current path, a step-up power supply circuit steps up and outputs a predetermined voltage based on a power supply start-up signal output by the internal power supply circuit, and the internal power supply switch opens a current path, and when the power supply is stopped, the step-up power supply circuit is stopped based on a stop signal output by the internal power supply circuit and the internal power supply switch closes the current path, and when the output voltage of the internal power supply circuit becomes lower than a predetermined value, the bias power supply switch closes the current path.

    Abstract: A voltage increasing control circuit is connected to a power supply (12) to regulate power supplied to a load (13). The voltage increasing control circuit includes a voltage increasing unit (30) configured to increase voltage that is supplied from the power supply (12), and to supply the voltage to the load (13). A power estimation unit (21 b) determines whether or not to increase the power supplied to the load (13). A voltage control unit (21 a) controls the voltage increasing unit (30). When the power estimation unit (21 b) determines to increase the power supplied to the load (13), the voltage control unit (21 a) controls the voltage increasing unit (30) to increase the power supplied to the load (13).
