  • Patent number: 4082987
    Abstract: The method is especially suitable for two identical groups of elements, and for supplying a continuous current traction motor. The commutating means modifies the coupling of groups of elements from parallel to series and conversely, as a function of the power demanded for driving the motor. The current supply of the motor is ensured by pulses delivered by a chopper type device monitored as a function of the power demanded. The commutating means e.g. a thyristor are actuated in synchronism with the operation of the chopper type device.
