Current conversion method and device and vehicle comprising such a device

Abstract

A power-conversion method for a vehicle including a three-phase electric motor, two three-phase inverters, each inverter being controlled via modulation of at least six spatial vectors, the output voltage of each inverter being given by a spatial vector referred to as “reference spatial vector”. The method includes the following steps: applying an activation sequence to the spatial vectors of one inverter, applying an activation sequence to the spatial vectors of the other inverter, subtracting the reference spatial vector of one inverter from the reference spatial vector of the other inverter and supplying the electric motor with electric power, the voltage inducing the electric power being relative to the vector resulting from the subtraction.
