Description
ある例示的実施形態では、各々が0.1MWを生成するモータ/発電機20を10個備えることにより、1MWのモジュール10(図1)を1つ提供する。ある例示的実施形態では、テザー組立品40から地上へ約20000Vを提供することを目的とするため、図8に示すように、システム100は、各々が約5000Vを生成するモジュール10を4個備える。約20000Vのテザー組立品40を得るために、各々が約500Vのモータを直列に10個つないでいる。
ある例示的実施形態では、500Vの代わりに、約1000Vを生成するモータ/発電機20が選択されている。この1000Vのモータ/発電機を2つで1組として1組ずつ並列につなぐとともに、5組を直列につなぐことによりモジュール10が、所望の500Vを生成するようにする。本方法では、モジュール10から同じ10MWを出力させるために1000Vのモータ/発電機を採用しているため、電流は小さくなる。電流を小さくすることで、より小さな電線や巻線を用いることができるため、結果として機械が軽量になる。このように、同じ1MWを出力するにもかかわらず、各モジュール10が引き出すアンペア数は半分である。電流を半分にすることで、より細かい電線のより小さな巻線を使用することができるため、結果としてモジュールが軽量になる。
ある例示的実施形態では、300個の「小さな」モータ/発電機が用いられ、4つのモジュール10から、約30000Vのテザー組立品40を提供する。4つのモジュール10から地上へ送り込まれた30000Vは、各モジュール10が約7500Vの出力を有するように変換される。各モジュールからの7500Vは300個のモータ/発電機に均等に分配されるため、結果として各モータ/発電機は約25Vを生成する。約25Vのモータ/発電機を直列に300個つなぐことにより、各モジュールから約7500Vが生成され、地上へ約30000Vが送り込まれる。ある実施形態では、モータ/発電機の中に冗長モータ/発電機がいくつか存在することにより、飛行中にいくつかのモータ/発電機が故障したときでも、十分な数のモータ/発電機が作動を継続し、システムにおいて、所望の計算された出力電圧を提供するようにしている。
