Abstract
A charging system charges a first voltage source and a second voltage source through an external charger. The first voltage source and the second voltage source are capable of supplying electric power to a rotating electric machine that includes a coil group configured by multiphase coils. The charging system includes a first inverter, a second inverter, at least three switches, and a control unit. The first inverter includes a first switching element. The second inverter includes a second switching element. The control unit is capable of switching charging between individual charging in which either of the first voltage source and the second voltage source is charged, and simultaneous charging in which the first voltage source and the second voltage source are both simultaneously charged, by controlling operations of the first switching element, the second switching element, and the switches.
