Design of a 400 Hertz inverter transformer by considering specific leakage inductance

Abstract

The conversion process in power electronics requires the use of transformer components that are frequently the heaviest and bulkiest item in the conversion circuit. They also have a significant effect upon the overall performance and efficiency of the system. Leakage inductance determination in transformer play a significant role in power electronic circuit. This paper present a procedure for designing a 400 Hertz inverter transformer whose leakage inductance is specific value due to playing the role of the output filter inductor or eliminate some harmonics to decrease the size of filter inductor. By the procedure presented here optimum core size and winding parameters could be specified. Analysis developed in this paper is validated by example case results and verified by finite element method (FEM) analysis which is made by Magnet.
