Abstract
The disclosure relates to a compact design method for inductive filtering transformer. According to the disclosure, the inductive filtering transformer adopts an approximative zero-impedance design under the premise of satisfying the filtering performance. The direct optimization objective is to minimize the distance from the transformer core center to the outermost winding. This disclosure balances the constraint of winding impedance matching and transformer size optimization and satisfies the application of limited installation space.
