Abstract
This paper introduces a generalized Space-Vector-Modulation (SVM) technique for n-phase Current-Source-Inverters(CSIs), where n is an odd number. Generally, for an n-phase CSI there are n 2 possible switching-states. Each state generates an output current space-vector. The resulted vectors are n(n - 1)active with (n - 1)/2 levels and n zero-vectors. These vectors are mapped in (n- 1)/2 subspace planes. Each plane is divided into 2n sectors with (n - 1)active- and n zero-vectors. The first-plane is called the fundamental-plane orαβ, while the others are called auxiliary-planes which are labeled by x 1 y 1 ·x 2 y 2 ··· etc. Two SVM methods are proposed based on the selected vectors. Moreover, generalized equations to determine the dwelling-times in both methods are proposed based on the ampere-second balance concept. In order to check the validity of the generalized-technique a case study for five-phase CSI fed an inductive-load is presented. A sample of simulation results is obtained to confirm the presented technique effectiveness.
