通过减少系绳处理装置和系绳阻力，系留水下航行器受益于尽可能小的系绳。如果车辆通过系绳供电，则最小的系绳通常会产生 1 至 3 kV 范围内的传输电压。交流输电系统可以使用变压器将高压转换为服务水平。水下航行器变压器的设计目标与传统变压器不同。重量是任何中性浮力飞行器的首要考虑因素，因此，为了追求更轻的重量，包括效率在内的大多数其他限制都被放宽了。设计从约束的优先级列表开始。然后，非线性优化可以将这些约束应用于控制变压器的基本电磁和热方程。结果是一个暂定的磁芯和绕组设计，可以与最初的目标进行比较，并进行迭代以实现任何必要的妥协。详细介绍了向车辆提供 20 千瓦直流电的 400 Hz、三相、油冷、压力补偿环形系统的示例设计。比较设计目标和“制造时”参数。一、简介
Tethered underwater vehicles benefit from the smallest possible tether through reduction of both tether handling gear and tether drag. If the vehicle is powered through the tether, a transmis- sion voltage in the range of one to three kilovolts usually results in the smallest tether. AC power transmission system can use trans- formers for conversion of the high voltage to service levels. Transformers for underwater vehicles are designed with different goals than conventional transformers. Weight is a prime consider- ation for any neutrally buoyant vehicle and thus most other con- straints, including efficiency, are relaxed in pursuit of lower weight. Design starts with a prioritized list of constraints. Non-linear optimi- zation can then apply these constraints to the basic electro-magnetic and thermal equations governing a transformer. The result is a tenta- tive core and winding design that can be compared with the original goals and iterated to achieve any necessary compronlises. An example design for a 400 Hz, three-phase, oil cooled, pressure compensated, toroidal system delivering 20 kilowatts DC to a vehicle is detailed. The design target and "as manufactured"' parameters are compared. I INTRODUCTION
