Abstract

Przedmiotem zgłoszenia jest reduktor napięcia łańcucha fotowoltaicznego, redukujący napięcie generowane przez łańcuch paneli fotowoltaicznych poniżej górnej granicy napięcia bezpiecznego dla człowieka, do wielkości korzystnie zbliżonej do zera. Reduktor ma równolegle do zacisków co najmniej jednego panelu fotowoltaicznego (PV<sub>1</sub>, PV<sub>2</sub>, ..., PV<sub>n</sub>) pomiędzy przewód dodatni prądu stałego (DC<sup>+</sup>) i przewód ujemny prądu stałego (DC<sup>-</sup>), ma włączony co najmniej jeden elektromechaniczny element łączeniowy (K, K<sub>1</sub>, K<sub>2</sub>, ..., K<sub>n</sub>) ze stykami o charakterystyce normalnie zwarte.
