| Abstract: |
| To overcome the shortcomings of traditional phase-shifting transformer winding design, such as complex design of winding, inaccurate turn’s ratio and difficult to expand, a linear phase-shifting transformer is applied to multi-module inverter system. The air gap magnetic field of linear phase-shifting transformer is analyzed. The basic principle of multi-module inverter system based on the linear phase-shifting transformer is introduced. At the same time, the winding structure is designed to weaken three-phase asymmetry and the efficiency of inverter system is improved by adjusting the air gap. Finally, the simulation and experimental verification are carried out. The results show that the designed inverter system provides three-phase AC sine voltage with high power quality, and the efficiency of the inverter system is relatively high. Hence, the feasibility of utilizing the linear phase-shifting transformer for multi-module inverter system is verified. |
