摘　　要：基于圆形移相变压器的12相多重叠加逆变器的工作原理,分析了在12相方波电压输入情况下,圆形移相变压器中的磁动势将近似为圆形旋转磁动势,因此在三相输出绕组中将得到近似的三相对称正弦电压.文中建立了该逆变器的数学模型,推导了参数计算公式,给出了简单的调压策略,并用Matlab对12相多重叠加的逆变过程进行了仿真.仿真结果表明,这种新型的12相多重叠加逆变器可以有效地减小输出的谐波,改善逆变器的输出性能,同时可以方便地调节输出电压.The operation of a Novel 12-phase multi-module inverter systems based on round phase-shift transformers is introduced in this paper.The composed magneto motive force（MMF）inside the round phase-shift transformer is theoretically proved to be approximately round rotating MMF when the 12-phase square wave form voltages are input into the round phase-shift transformers.As a result,the symmetrical sinusoidal three-phase voltages are produced in the output three phase windings of the round phase-shift transformers.Mathematic model of the novel transformer is set up and the main performances were analyzed by simulation in Matlab.The results of simulation show that the novel multi-module inverter is effective in reducing the harmonic in the output voltage and convenient in regulating the amplitude of the output voltage.
