DEVICE FOR DRIVING A CLOSURE OR SHADING MEMBER IN A BUILDING BY MEANS OF A SOLAR ENERGY SOURCE
Disclosed is a device for driving a closure member (9) in a building by means of a solar energy source (1), comprising at least one low-voltage AC electric motor (3) mechanically coupled with the closure member, a DC electrical energy storage element (2) and a solar energy source delivering a DC electrical voltage. The electrical energy storage element has a nominal voltage less than said effective electrical voltage and greater than the DC electrical voltage delivered by the solar energy source. A DC-DC charger (4) converts the electrical energy from the output of the solar energy source into an electrical energy at the electrical charging voltage of the electrical energy storage element. A DC-AC converter (5) transforms the output electrical energy with DC electrical voltage of the electrical energy storage element into an electrical energy with AC voltage capable of supplying the electric motor.
