Abstract：The linear phase-shifting transformer had broken magnetic circuit,leading to side effect and distortion of air gap magnetic field. Firstly, the basic principle of linear phase-shifting transformer was described, two kinds of longitudinal side effect were analyzed, the magnetic potential distribution was deduced, the analytical expression of the air gap magnetic field was obtained, and the parameters affecting the distortion degree of the air gap magnetic field were obtained. The distribution of magnetic potential and gas gap magnetic fields of linear phase-shiftimg transformer were verified by simulation. The influence of relevant parameters of phase-shifting transformer on side effect was analyzed quantitatively. Finally, finite element simulation and prototype experiment were used to analyze the output performance of multiple superposition inverter system based on linear phase-shifting transformer under different loads, which further proves that the influence of two kinds of longitudinal side effects on air gap magnetic field and working performance can be effectively reduced by selecting proper transformer design parameters.
