摘　　要：探讨了中点箝位三级桥臂和通常的由上、下元件桥臂组成的单相逆变桥工作原理，用较少的元件输出5电平，有利于减小谐波，仿真证明是可行的。Basic operation principle of a single-p hase inverter bridge with a neutral-point clamped three-level arm and an arm consisting upper and lower device is explored. Its output is a five-level vokage, which is in favor of reducing harmonics. Simulation results show that it is feasible..
