In order to overcome the shortcomings of traditional AC-DC-AC electrical driving systems, a dual-PWM method for the three-level voltage source converter to drive an induction motor (IM) is proposed in this chapter. In the rectifier part, this chapter presents the inner current-loop and the outer voltage-loop control strategy based on voltage space vector (SVPWM); in the inverter part, this chapter proposes the current-loop and the speed-loop control strategy based on SVPWM and rotor flux oriented. By applying the dual-PWM method, the system can get unity input power factor, minimize both input and output current harmonics, achieve bidirectional flow of energy, and enhance dynamic performance of the speed control. At last, both simulation and experimental results verify the feasibility and usefulness of this control method.
