Single-pole switching unit for limiting the energy flow in a series circuit comprising photovoltaic modules, photovoltaic module arrangement and photovoltaic module |
摘要 |
In various embodiments, a single-pole switching unit for limiting the energy flow in a series circuit having photovoltaic modules by a pulsating control signal present on at least one DC line is provided. The switching unit may include: a switching element, which is designed to reduce the current flow in the at least one DC line of the photovoltaic modules; a transmission element, which is designed to couple out an electrical control signal present on the DC line and to control the switching element merely with the energy of the coupled-out control signal; and a coupling element, which is arranged in parallel with the switching element and which conducts the control signal through the switching unit when the switching element is nonconducting.
