摘要
Abstract
In allusion to problems such as high total harmonic distortion (THD) value,large switching loss,neutral voltage drift,and so on of neutral point clamped (NPC) inverter in its actual application,a new-typed modulation strategy based on vector combination columns is presented.By combining single vector into a group of sequence and using half-wave symmetry method to combine the vector sequence,a kind of modulation strategy is produced for reducing THD value and switching loss,restricting neutral point drift and improving voltage use ratio and power energy quality.Simulation and experiment results verify advantages and feasibility of this new-typed modulation strategy.关键词
