Abstract: An exemplary system for energy optimization in photovoltaic generators comprises a plurality of primary photovoltaic generators, a plurality of secondary photovoltaic generators, and a plurality of inverters. The secondary photovoltaic generators each comprise a plurality of photovoltaic generator blocks. The inverters are configured to convert direct voltage/current into alternating voltage/current. A first switching system is operable to selectively couple outputs of the primary generators with inputs of the inverters. A second switching system is operable to selectively couple outputs of the generator blocks with the outputs of the secondary generators. A control system is operable to automatically control the first switching system and the second switching system. An exemplary method comprises operating the control system to automatically control the two switching systems to optimize power provided to the inverters.

Abstract: A system for the manufacture of electrical coils. The system includes a control unit configured to receive measurements for the electrical coil. The system further includes a pressure head operably connected to the control unit and mounted on a support, the pressure head including a vertical axle and a horizontal axle. At least one vertical wheel is mounted on the vertical axle and positioned to accept a conductor material and regulate height and flatness in the coil being formed. At least one horizontal wheel is mounted on the horizontal axle and positioned to accept the conductor material and position the conductor material on top of a previously formed coil. At least one hydraulic cylinder is attached to the vertical and horizontal axles and configured to adjust coiling pressure exerted on the conductor material by adjusting hydraulic pressure on the axles.

Abstract: A semi-automatic system for the manufacture of large electrical induction coils comprises a table for the manufacture of coils which is worked on by means of an articulated head that exerts the necessary pressure on each of the turns in the coil and is aided by a system that tightens and feeds the conductor, being controlled by a remote programmed system wherein the relevant orders are entered for the characteristics of the coils to be manufactured. Said system makes the manufacturing cycle much shorter since it removes the need for jobs that are currently carried out by hand, such as controlling the coil size and pressing the coils, therefore achieving greater precision in the size of coil required. This process regulates and controls the mechanical tension of the conductor, avoiding the risk of stretching or distortion thereof and thus producing better quality coils.
