摘要： Fluctuations in output of an AC electric motor are restrained without increasing electromagnetic noise of a boost converter. When subjecting the AC electric motor to rectangular wave voltage control, output torque T is controlled by varying a voltage phase φv. In a region where a voltage phase is large (φv=θ2), fluctuations in torque T relative to changes in a DC voltage VH corresponding to the amplitude of a rectangular wave voltage are larger than in a region where the voltage phase is small (φv=θ1). The AC electric motor is controlled such that the rectangular wave voltage control in a region where voltage phase φv is larger than a limit-phase line PLN indicated by a set of limit phases set for each DC voltage VH is avoided.

摘要： A power supply system that supplies electric power to a load includes a first power storage device, a second power storage device, a power line for transmitting electric power input and output to and from the load, a converter for executing bidirectional DC voltage conversion between the first power storage device and the power line, and a switch connected between the second power storage device and the power line. When the switch is OFF, the control device performs voltage control of the converter so that a voltage value of the power line becomes a voltage command value, and when the switch is ON, the control device performs current control of the converter so that a current value of the first power storage device becomes a current command value.
