摘要： A torque command (Tht) used in the calculation of a voltage command (Vht) of a voltage-up converter is generated by adding an upper limit value value (Tc_max) of damping control that can be set by a motor drive device with a target drive torque (Tbt). Accordingly, the torque command (Tht) exhibits a waveform absent of variation, differing from a torque command (Tcmd) that is generated by adding damping torque generated based on revolution count variation component with the target drive torque (Tbt). Therefore, the voltage command (Vht) calculated based on the torque command (Tht) exhibits a waveform absent of variation. Accordingly, increase in current passing through the voltage-up converter caused by variation in the voltage command (Vht) can be suppressed. As a result, power loss at the voltage-up converter is reduced and operation of the motor at high efficiency can be realized. Further, the voltage-up converter can be protected from element fracture.

摘要： An AC/DC converter is configured to perform voltage conversion on power supplied from an AC power supply and supply the power to an auxiliary load during external charging in which a main power storage device is charged by the AC power supply. An auxiliary power storage device stores power to be supplied to the auxiliary load. A diode permits discharging of the auxiliary power storage device while preventing charging of the auxiliary power storage device during the external charging. A current sensor detects discharging of the auxiliary power storage device. A controller adjusts an output voltage of the AC/DC converter while confirming whether or not the auxiliary power storage device discharges, based on a detection value of the current sensor.

摘要： A power supply device includes: a magnetic-coupling-type multi-phase converter having first and second chopper circuits that respectively adjust respective currents flowing in first and second reactors magnetically coupled to each other, and performing voltage conversion between a DC power supply and a load; and a control circuit. The control circuit includes a determination unit and a current control unit. The determination unit determines whether the temperature of the power supply is lower than a reference temperature. In the case where the power supply temperature is lower than the reference temperature, the current control unit uses a value determined by adding an offset amount to a detected value of the reactor current to set a duty command value for the first chopper circuit and uses a detected value of the reactor current to set a duty command value for the second chopper circuit.

摘要： An AC-DC converter converts an alternating-current voltage, supplied from an external power supply, to a direct-current voltage higher than a peak voltage of the alternating-current voltage, and outputs the direct-current voltage to a first power supply line. In a normal control mode, a DC-DC converter steps down a voltage of the power supply line through on/off control over a switching element to charge a main battery. On the other hand, in an upper arm ON control mode, the DC-DC converter charge the main battery while the switching element is kept in an on state. On the basis of a state of external charging, a control device applies the upper arm ON control mode when a condition that upper arm ON control is applicable is satisfied, and applies the normal control mode when the condition is not satisfied.
