摘要：

To solve the implementation complexity problem of single-phase 5-L/7-L converter space vector pulse-width modulation (SVPWM) algorithm, a simplified space vector pulse-width modulation algorithm is proposed. The proposed algorithm simplified the calculation of single-phase 5-L/7-L SVPWM to single-phase 3-L SVPWM by dividing the voltage vector space of single-phase 5-L/7-L SVPWM into different single-phase 3-L SVPWM voltage vector space and decomposing the reference voltage vector into different voltage vectors. The computational complexity and resource consumption of micro controller chip based on the proposed algorithm is less than the conventional algorithm, and the capacitor voltage balancing scheme can be implemented easily. The proposed single-phase 5-L/7-L SVPWM and conventional single-phase 5-L/7-L SVPWM for cascaded H-bridge (CHB) converter and neutral point clamped (NPC) converter were realized on a single field programmable gate array (FPGA) to verify correctness and effectiveness of the proposed algorithm. © 2019, Harbin University of Science and Technology Publication.
