An apparatus for driving and controlling a car has a large gear directly connected to a wheel shaft of the car, small gears meshing with the large gear, AC motors connected to the small gears, respectively, and inverters whose AC output sides are connected to the AC motors, respectively, and whose DC input sides are connected in series in multiple stages to a high-voltage DC power source. Torque for driving the large gear connected to the wheel shaft is divided and borne by the small gears, so that each small gear receives small torque. This enables each tooth of each gear to have small mechanical strength. As a result, the cross-sectional area of each tooth of each small gear can be reduced to increase the number of teeth of the large gear that meshes with the small gears, to increase a gear ratio defined by the large and small gears. The DC input terminals of the inverters are connected in series to the high-voltage DC power source, and a DC input voltage for each inverter is reduced to a standard inverter level. Consequently, the inverters of the apparatus may be mass-produced standard inverters.
