摘      要：Three-dimensional space vector modulations (3-D SVMs), while inheriting the advantages of two-dimensional space vector modulations (2-D SVMs), have the capability to generate asymmetrical currents, making them widely applied in four-leg inverters. However, the computational burden due to the expansion of space and vectors adds potential limitations to the application of 3-D SVM. To overcome this limitation, this article proposes a simplified 3-D SVM based on the abc coordinate system, which is designed for four-leg current source inverters. The recognition of tetrahedra and the calculation of duration time is simplified through thoughtful design. This algorithm avoids irrational operations and table lookups, eliminates pointer function calculations, and alleviates the computational burden on the processor. Experimental results validate the effectiveness of the proposed 3-D SVM.
