  • Overvoltage protection for inverters that comprise an EMC filter at their input end
    Patent number: 8570692
    Abstract: In an overvoltage protection apparatus before an inverter configured to feed electric energy from a DC voltage source into an AC power grid, the overvoltage protection apparatus includes a DC voltage input stage. The DC voltage input stage includes at least two current-carrying lines and an EMC filter including interference suppressing capacitors and interference suppressing inductors, and surge arrestors configured to divert overvoltages with respect to ground are connected to the current-carrying lines after the EMC filter, from a point of view of the DC voltage source.
    Type: Grant

  • Circuit arrangement with a relay incorporating one field coil as well as switch contacts
    Patent number: 8023242
    Abstract: The invention is directed to a circuit array with a relay (K1; K12) incorporating a field coil (E) as well as a switch contact (1a, 1b), said switch contact (1a, 1b) being provided as a switch point between a grid, in particular a mains supply (N), and an inverter (WR) fed by a direct voltage source, in particular by a photovoltaic generator (PVG), said relay (K1; K12) being configured to be a bistable relay.
