摘　　要：针对能量变换器的空载电势波形计算问题,采用时步有限元法求解瞬态涡流场,进行 了空载电势波形的仿真计算,得出了电势波形畸变率．仿真结果与实验结果基本吻合,表明采用时 步有限元法计算空载电势波形是可靠的．To solve the problem of calculation of no - load EMF waveform for powerformer, time - stepping FEM is proposed to solve transient eddy field, no - load EMF waveform and distortion of powerformer are obtained. The simulating result accords with test result. The result shows that time- stepping FEM is a reliable method on calculating no -load EMF waveform of powerformer.
