This paper introduces a novel technique for simplification of a three-dimension space vector pulse width modulation (3D-SVPWM). Conventional SVPWM calculations are based on trigonometric functions or several decomposition matrices. Thus, a very fast embedded controller is needed either for two-dimension space vector pulse width modulation (2D-SVPWM) or 3D-SVPWM. The proposed simplified 3D-SVPWM is dedicated to four-wire three-leg inverters. This technique is based on first-order equations of the curve fitting technique to reduce calculation time. Therefore, this method can be implemented with low memory storage and Central Processing Unit (CPU) capability. In addition, high accuracy can be achieved using higher-order equations. Many approaches are introduced for simplifications. The applications of the proposed simplified 3D-SVPWM method are also provided. Simulation results of the proposed simplified 3D-SVPWM and the conventional 3D-SVPWM are discussed. Finally, the results are verified using a real-time simulator based on Typhoon device (402) as Hardware-In-the-Loop. In addition, the controller of the simplified method is implemented and operated on the C2000 LAUNCHXL-F28379D as a low-cost microcontroller kit.

四线三脚逆变器的3D-SVPWM简化方法

本文介绍了一种用于简化三维空间矢量脉宽调制 (3D-SVPWM) 的新技术。传统的 SVPWM 计算基于三角函数或多个分解矩阵。因此，二维空间矢量脉宽调制 (2D-SVPWM) 或 3D-SVPWM 都需要非常快速的嵌入式控制器。提议的简化 3D-SVPWM 专用于四线三腿逆变器。该技术基于曲线拟合技术的一阶方程，以减少计算时间。因此，这种方法可以用低内存存储和中央处理单元 (CPU) 能力来实现。此外，使用高阶方程可以实现高精度。为了简化，引入了许多方法。还提供了所提出的简化 3D-SVPWM 方法的应用。讨论了所提出的简化 3D-SVPWM 和传统 3D-SVPWM 的仿真结果。最后，使用基于 Typhoon 设备 (402) 作为硬件在环的实时模拟器来验证结果。此外，简化方法的控制器作为低成本微控制器套件在 C2000 LAUNCHXL-F28379D 上实现和运行。
