A motor control system using an inverter voltage control method is provided to enable precise torque control of a large-capacity motor and reduce switching loss due to a decrease in a switching frequency. A motor control system using an inverter voltage control method includes a battery, an inverter, a three-phase motor, and a motor control unit. The inverter is a 150-degree conductive inverter using 13 voltage vectors. The motor control unit includes a dual band Hysteresis current controller. The dual band Hysteresis current controller is a five-level Hysteresis current controller. The 13 voltage vectors are composed of 12 effective voltage vectors(V1-V7) and one zero voltage vector(V0,V7). |
