摘要： The present invention relates to the field of photovoltaic systems with solar cell (s) or modules having insolation differences or mismatch. Each solar module is formed by placing a large number of solar cells in series. The PV system is then formed by placing a number of solar modules in series in a string and sometimes by placing multiple strings of series-connected solar modules in parallel, depending on the desired output voltage and power range of the PV system. In practical cases, differences will exist between output powers of the solar cells in the various modules, e.g. due to (part of) the modules being temporarily shaded, pollution on one or more solar cells, or even spread in solar-cell behaviour that may become worse during aging. Due to the current-source-type behaviour of solar cells and their series connection these differences will lead to a relatively large drop in output power coming from the PV system. This invention addresses this problem by adding DC-DC converters (803) on a single or multiple solar-cell level that source or sink difference currents thereby increasing the output power of the complete PV system. In embodiments, the efficiency of photovoltaic systems with solar cell (s) or modules is improved by compensating for output-power loss caused by insolation difference and mismatch.
摘要翻译：本发明涉及具有太阳能电池或具有日照差异或不匹配的模块的光伏系统领域。每个太阳能模块通过串联放置大量太阳能电池而形成。然后通过将多个太阳能模块串联放置在串中并且有时根据PV系统的期望的输出电压和功率范围并联放置多串串联的太阳能电池组件来形成PV系统。在实际情况下，在各种模块中的太阳能电池的输出功率之间将存在差异。由于（部分）模块暂时阴影，对一个或多个太阳能电池造成污染，甚至在太阳能电池行为中蔓延，在老化过程中可能会变得更糟。由于太阳能电池的电流型行为及其串联，这些差异将导致来自光伏系统的输出功率相对较大的下降。本发明通过在单个或多个太阳能电池级别上添加DC-DC转换器（803）来解决这个问题，源或汇差电流从而增加了整个PV系统的输出功率。在实施例中，通过补偿由日照差和失配引起的输出功率损耗来提高具有太阳能电池或模块的光伏系统的效率。

摘要： A method is disclosed of controlling a LED, comprising driving the LED with a DC current for a first time, interrupting the DC current for a second time such that the first time and the second time sum to a period, determining at least one characteristic of the LED while the DC current is interrupted, and controlling the DC current during a subsequent period in dependence on the at least one characteristic. The invention thus benefits from the simplicity of DC operation. By operating at the LED in a DC mode, rather than say in a PWM mode, the requirement to be able to adjust the duty cycle is avoided. By including interruptions to the DC current, it is possible to utilize the LED itself to act as a sensor in order to determine a characteristic of the LED. The need for additional sensors is thereby avoided.

摘要： Consistent with an example embodiment, there is a method of controlling a synchronous rectifier having an input signal having oscillations therein and a switch which is switchable between an open state and a closed state. The method comprises filtering the input signal to produce a filtered signal, comparing the filtered signal with a reference value, and opening the switch in response to the comparison, in which the filtering is active filtering.The active filtering may be based on determination of the peaks (positive and/or negative) of the signal, either directly, including a quarter period offset, or including decay—or a combination of the above; alternatively, the active filtering may be based on the a smoothing functions such as a switched low-pass filter or a short time integrator.

摘要： Method and apparatus for controlling the rotation velocity of an optical disc in a wide range of velocities, including low velocities. In a first range of velocities, a first sensor, for example an EMF sensor, is used to control the commutation moments of a turntable motor. For velocities outside the first range, a periodic control signal based on a periodic second signal generated by a second sensor and a mapping between the first and second periodic signal are used. The method and the apparatus are suitable for LightScribe™ applications.
