摘要：
The input-series converters based on transformer-integration have the advantages of active input voltage sharing of each series-module and simple structure, which are suitable for high-input voltage multiple-output applications. In the high voltage applications, these converters can be affected seriously by the energy stored in their integrated-transformers' stray capacitances. Taking this type of input-series two-transistor flyback converter as the object, the influence of the integrated-transformer's stray capacitances was investigated. Energy storage of stray capacitances in the primary windings of the integrated-transformer was analyzed, and a winding layout scheme of the integrated-transformer was proposed to suppress the influence of stray capacitances. Finally, experiments were carried out on an experimental prototype of this type of input-series converter, which verified the theoretical analysis and feasibility of the proposed scheme. © 2021, Electrical Technology Press Co.
