MULTI-AXIS CONVERTER OF ELECTRIC DRIVE Russian patent published in 2018 - IPC H02P5/74 B60K6/20 B60L9/12 B60L15/20 B60W10/08 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering and can be used in a multi-engine electric vehicle, for example in a wheelchair, a treble, an electric vehicle. Multi-axis converter of the electric drive of an electric vehicle for two or more number of three-phase synchronous motors with excitation from permanent magnets, including the reversed design (motor-wheel) contains power amplifiers, for example transistor ones in the number of axes (two or more), preliminary amplifiers (drivers) according to the number of axes. PWM control of these channels is performed by a single microprocessor common to all axes; phases of the carrier signal PWM channel control are offset by an interval determined by the control period divided by the number of axes.

EFFECT: technical result is the improvement of mass and size and energy indicators.
