FIELD: transportation.
SUBSTANCE: hybrid vehicle contains an on-board power source, a power storage device, a storage device power converter into three-phase alternating voltage and a wheel electric driving motor. There are also power converters and wheel drives. The power storage device is connected to the on-board power source which contains the batteries connected in series. Each converter contains six transistor switches. The emitters of the first, second and third keys are connected to the collectors of the fourth, fifth and sixth keys and are connected in the first common point connected with the energy storage device. The collectors of the fourth, fifth and sixth keys are connected to the second common point connected to the midpoint between the batteries of the storage device. Each electric drive of the wheels contains an asynchronous motor whose stator windings are connected in a star. The start of the first, second and third windings is connected to the emitter of the second, first and third keys, respectively. The ends of the windings are connected to the power storage device. The key bases are connected to the outputs of the microcontroller unit.
EFFECT: higher vehicle reliability.
