摘　　要：探讨了用单相整流器的半桥和中点箝位三级逆变器的半桥来作逆变用的单相变频器。其特点是用很少的元器件，成本低，可靠性较高，并作了Matlab／simulink仿真证明是可行的。缺点是输入电流畸变大，因此只适用于小功率需变频的装置。Single phase （SP） static frequency changer with half of a SP rectifier bridge and half of a SP Neutral-Point Clamped Three-Level Bridge Inverter is explored. It uses less device, cost low and with higher reliability . Simulation results show＂ that it is feasible. Its shortcoming is distortion of input current so, that is suitable to use for low power device needing frequency change
