Abstract
Description
− 海洋構造物の表面に配置された、及び、電源の一方の極性部に結合するために構築された伝導体構成体であって、電源の他方の極性部が、電気伝導媒体に結合された、伝導体構成体と、
− 液体に接触する前面と、伝導体構成体と海洋構造物の表面との一部をカバーする後面とを含むキャリアと、
を備え、
キャリアが、
− キャリア内に配置された、及び、電源から電源電流を受信するために第1の給電ノードと第2の給電ノードとの間に結合された負荷と、
− 第1の給電ノードに接続された、及び、電気伝導媒体に結合するために配置された前面における前電極と、
− 第2の給電ノードに接続された、及び、伝導体構成体に結合するために配置された後面における後電極と、
を備える。
− 伝導体構成体が、海洋構造物の表面に配置されており、
− キャリアが、伝導体構成体と海洋構造物の表面との一部をカバーする後面を含んで、海洋構造物の表面に配置されており、
− 後電極が、伝導体構成体に結合されており、
海洋構造物が、
− 伝導体構成体に接続された一方の極性部と、電源から負荷に電源電流を伝達するための電気伝導媒体に結合された他方の極性部とを含む電源
を備える。
− 液体にさらされる海洋構造物の表面に伝導体構成体を装着することと、
− 伝導体構成体と海洋構造物の表面との一部をカバーするキャリアの後面を配置するとともに、伝導体構成体に後電極を結合することと、
− 電源から負荷に電源電流を伝達するための、電気伝導媒体と伝導体構成体との間に結合された電源を提供することと、

C=ε0εrA/d
により与えられ、ここで、Aは表面であり、dはプレートから海水までのギャップの厚さであり、(キャリアの材料としてのシリコーンの場合)ε0=8.854×10−12F/mであり、εr=2.75である。ギャップが0.1mmの間であり、プレート表面が50×50mm2である場合、カップリングコンデンサの値がC=6×10−10Fである。f=100kHzの周波数の場合、AC抵抗は
Z=1/iωC
により与えられる。従って、このコンデンサに対する|Z|の典型的な値は、|Z|=2.6kOhmである。これは、約6V/15mA=400OhmであるUVC LEDの典型的な抵抗より大きい。従って、LEDの単一の集合が使用される場合、これは、容量性結合器の抵抗に起因して大幅な電力損失につながる。より高い振動数(例えば>2MHz)において、結合器の抵抗はより小さいので、電力損失が小さくなる。
Z=iωL+1/iωC
により与えられ、
|Z|=(1−ω2LC)/ωC
となる。|Z|の値は
