对美国专利 5,124,904 中描述的基于具有三个输出的差动三角形/叉形自耦变压器连接的 18 脉冲整流器系统进行了分析和测试。这种拓扑结构不需要相间变压器，并且可以符合当前的航空航天电能质量规范，但会带来一些问题，例如此类电路中常见的固有阻抗失配。为了克服这些问题，提出了电流平衡技术的设计、分析和实际性能。
An 18-pulse rectifier system based on the differential delta / fork autotransformer connection with three outputs, described in US patent 5,124,904, is analysed and tested. This topology does not need interphase transformers and can comply with current aerospace power quality specifications but presents some problems like inherent impedance mismatches, typical in this type of circuit. To overcome these problems, the design, analysis, and practical performance of a current-balancing technique is presented.
