Abstract

Abstract

Solid insulating materials may increase the leakage flux of insulated core flat winding transformer(ICFWT). This results in a low generated voltage in the secondary coils, especially on the upper stages. Parallelly connecting an appropriate compensation capacitor to the secondary coil on every stage will cancel the flux loss. Design equations to calculate the value of flux compensation capacitors and relevant simulations by CST and Protel are presented. Simulation results of an actual ICFWT show that the output voltage increases by 17.6% with compensation. At the same time, every stage generates almost the same voltage. Simulation results are consistent with the results of subsequent experimental tests, which again confirms the effectiveness of flux compensation capacitors.
