Abstrakt

This paper presents a model-based implementation of modified space vector modulation (SVM) for a three-level three-phase active neutral-point clamped (ANPC) rectifier. To optimize and reduce the number of high frequency active switches, this paper uses a hybrid modulation technique in which only two switches out of 6 active switches are switching at high frequency and the rest are working at fundamental frequency (50 Hz). However, using space vector-based hybrid modulation for ANPC introduces several limitations on selecting the output vectors such as zero-vector that is generated by connecting all three phases to the positive DC rail. To deal with this issue, a modified hybrid SVM is utilized to adjust the voltages of the DC link. A prototype is made using Gallium-nitride (GaN) FETs and the modified SVM is implemented in a field programmable gate array (FPGA). To show that the modified SVM can control the DC link voltages, an experimental comparison is carried out between a carrier-based modulation and the modified SVM.
