三相电压型PWM逆变器常采用基于电流前馈解耦的电压电流双闭环控制策略。采用该控制策略，电流内环控制器设计时包含交流侧电感值，当电感测量值出现误差时，系统将不能彻底解耦，会影响系统的控制性能。提出一种改进型电压电流双闭环控制策略，其中电流内环基于合成矢量的思想，实现在同步旋转d、q坐标系下三相电压型PWM逆变器无电感参数L的电流解耦控制，采用MATLAB/Simulink仿真验证了该方法的有效性。

Three-phase voltage-sourced PWM inverter achieves better control performance by using the double closed loop control strategy, which is based on current feed-forward decoupling control strategy. When the measured value of the inductor is wrong, the system can’t be completely decoupled. A new double closed loop control strategy was put forward, which was composed of decoupling current controller without exact value of the inductor. The suitable control strategy of three-phase voltage-sourced PWM inverter was attained in MATLAB/Simulink simulation.
