A T-S converter is composed of a first rotor which has a first control coil, a second rotor and a stator which has a second control coil. The second rotor has a first magnetic field member (such as permanent magnets) which supplies the first control coil with magnetic field and a second magnetic field member (such as permanent magnets) which supplies the second control coil with magnetic field. The first and second control coils are energized to drive the second rotor to rotate at a set speed with a set torque according to vehicle running condition. The first and the second control coil are also energized to generate battery charging current when the vehicle speed is decreased and the second rotor is driven by the vehicle wheels.
