摘　　要：分析三电平中点箝位型(NPC)逆变器调制策略,介绍一种以载波交叠策略调制三电平逆变器的线性度的方法,利用仿真模拟及实验测试、比较了载波交叠法(COPWM)与载波交叠+载波线性校正的调制策略。This paper analyses a three-level midpoint clamp（NPC） inverter modulation strategy and introduces a method of adjusting the linearity of three-level inverters with carrier-overlapping. By using simulation and experimental tests, modulation strategy of carrier-overlapping method（COPWM）and carrier-overlapping carrier linear correction is compared.
