To improve the efficiency of high-frequency link inverter of transformer, the working characteristics were researched, the appearance of transformer saturation and core loss of high-frequency link inverter of transformer was studied by SPWM wave by the simulation model of voltage transformer. The simulation model of voltage transformer was designed by Ansoft /Maxwell finite-element simulation analysis software, the different modulation ratios and carrier ratios of SPWM wave impact on voltage transformer were analyzed, and the characteristics of exciting current under different primary voltage and core loss were also analyzed. It provides the basis to design the high-frequency link inverter of transformer.
