Optimized SVPWM Modulation Strategy for a Three-Phase Two-level Voltage Source Converter Based on Simplified Basic Vectors

Among the existing modulation strategies, SVPWM has attracted much attention due to its high DC voltage utilization and good dynamic performance. However, the traditional SVPWM algorithm is computationally complex, has low operational efficiency, which limits its promotion in practical applications. To address these issues, this paper takes the three-phase two-level voltage source converter as the research object and proposes an optimized SVPWM modulation strategy based on simplified basic vectors. The effectiveness of this strategy in optimizing SVPWM and maintaining a single power factor operation on the AC side is verified through simulation analysis.
