20080198523 | Circuit Breaker for a Solar Module - A circuit breaker for a solar module, wherein a plurality of solar cells working in normal operation and when shaded are connected in series. At least one controlled electrical switch element serves as a bypass element and is connected in parallel with its contact gap to a plurality of solar cells. A supply circuit provides a control voltage for controlling the control electrode of the bypass element. An isolating circuit blocks the voltage applied to the contact gap of the bypass element in the normal operation and switches the voltage that is applied to the contact gap to the supply circuit when at least one solar cell is shaded. | 08-21-2008 |

20100295381 | Controllable Change-Over Apparatus for a Solar Module - Controllable change-over apparatus for a solar module comprises an output terminal, a DC/DC converter, a controllable switching device and a control. The controllable switching device is implemented with a first switch position and a second switch position, wherein, in the first switch position, a power output of the solar module is connected to the output terminal via the DC/DC converter, and, in the second switch position, the power output of the solar module is connected to the output terminal by bypassing the DC/DC converter. The control switches the controllable switching device by using a performance characteristic for switching the same to the first or second switch position. In particular, the control is implemented to connect the solar module directly to its output terminal in the case of high power dissipation of the same, i.e. at strong solar radiation, and to connect the solar module to the output terminal via the DC/DC converter in the case of weak power dissipation of the same, i.e. during shading, which significantly increases the efficiency compared to a fixed connection of the solar module. | 11-25-2010 |
