Steuerbare Umschaltvorrichtung fuer ein Solarmodul

DE 102008004675 B3 UPAB: 20090327 NOVELTY - The device (100) has an output terminal (102), a direct current-to direct current (DC/DC)-converter (105), and a controllable switching unit (103) with two switch conditions, where an output (110) of a solar module (101) is connected to the terminal via the DC/DC-converter in one of the switch condition. The output is connected to the terminal through the DC/DC-converter in other switch condition. A control (104) controls the switching unit to switch the switching unit in one of the switch conditions using the output of the solar module or an input (111) at the terminal. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) a method for controlling a controllable switching device for a solar module (2) a computer program with program code for implementing a method for controlling a controllable switching device for a solar module when the program runs in a computer. USE - Controllable switching device for a solar module that is utilized for converting electromagnetic radiation i.e. light of sun, into electrical energy in a photovoltaic system, small main supply-independent consumer and for power supply of a spacecraft. ADVANTAGE - The control controls the switching unit to switch the switching unit in one of the switch conditions using the output of the solar module or the input at the output terminal, so that the control is directly connected with the output terminal of the control in case of high power output of the solar module i.e. during strong solar irradiation, and with the output terminal via the DC/DC transducer in the case of weak power output of the solar module i.e. during shadowing, thus enabling efficient control of the controllable switching device, and hence precisely increasing the efficiency of the solar module
