摘　　要：在航空低压大电流场合,常采用模块并联来满足输出功率,提高系统可靠性。在并联系统中,首要需要考虑系统的均流特性,保证系统的可靠运行。传统的均流方式主要是外加均流电路对模块进行均流。本文通过矩阵变压器,提出了一种新的均流方式,基于原电源变换装置,设计了矩阵变压器的磁心、绕组,并对变压器损耗进行计算,最后对其均流特性进行实验验证。In aviation low-voltage and hi gh-current occas ions,modules are often used in parallel to meet the output power and improve system rel iability.In a parallel system,the first need to consider the current sharing characteristics of the system to ensure the reliable operation of the system.The traditional current sharing method is mainly to add a current sharing circuit to share the current of the module.In this paper,a new current sharing method is proposed through the matrix transformer.Based on the original power conversion device,the core and winding of the matrix transformer are designed,the transformer loss is calculated,and the current sharing characteristics are experimentally verified.
