ENTRUST provides mapping of Europes energy system (key actors & their intersections, technologies, markets, policies, innovations) and an in-depth understanding of how human behaviour around energy is shaped by both technological systems and socio-demographic factors (esp. gender, age and socio-economic status). New understandings of energy-related practices and an intersectional approach to the socio-demographic factors in energy use will be deployed to enhance stakeholder engagement in Europes energy transition. The role of gender will be illuminated by intersectional analyses of energy-related behaviour & attitudes towards energy technologies, which will assess how multiple identities and social positions, combine to shape practices. These analyses will be integrated within a transitions management framework which takes account of the complex meshing of human values and identities with technological systems. The third key paradigm informing the research is the concept of energy citizenship, with a key goal of ENTRUST being to enable individuals overcome barriers of gender, age and socio-economic status to become active participants in their own energy transitions. Central to the project will be an in-depth engagement with 5 very different communities across the continent, who will be invited to be co-designers of their own energy transition. The consortium brings a diverse array of expertise to bear in assisting and reflexively monitoring these communities as they work to transform their energy behaviours, generating innovative transition pathways and business models capable of being replicated elsewhere in Europe. Deliverables will include a policy tool-kit incorporating contemporary best practice in promoting energy transitions at a Europe-wide level; a suite of innovative transition pathways and community engagement tools designed to stimulate dialogue and break down barriers to behaviour change and the adoption new technologies at a community level.

A modular and scalable structure that can perform current-balancing multiple LED strings is presented. The current-balancing function is accomplished by connecting multiple transformers in a daisy chain-the primary and secondary windings of each transformer are connected to two different modules, and thus the two module currents are mutually coupled. The modules are shared with the same input, derived from the output of a switching network, and each module is used to drive an LED string. When there is a fault occurred in a string, such as open-or short-circuit of any LED, such string will be disconnected from the corresponding module. As the output voltage of the module will then increase under such situation, an energy-recycling circuit with each module having an OR-ing diode connected to its input will be activated to clamp the module voltage by recycling energy back to the source. Thus, the faulty string(s) will not affect the normal operation of the healthy strings. A prototype with seven 1 W LED strings has been built and evaluated. Experimental results show that the string current has less than ±1% variation under different dimming levels, string voltage variation of ±30%, and faulty operations in some LED string(s). © 2013 IEEE.

A method for correcting long-term phase drift of a crystal oscillator in a numerically-controlled oscillator is described. The method includes determining the phase error in an oscillator signal in comparison with an external time base; delta-sigma modulating the phase error to generate a delta-sigma error bitstream; conditionally adding or subtracting an error correction step size from a phase increment value in each clock cycle based on the delta-sigma error bitstream, to create a modulated phase increment value; and adding the modulated phase increment value to a phase accumulator to generate an error-corrected output digital signal. The delta-sigma-based error correction method avoids the use of multipliers. The same delta-sigma error signal can be used in multiple numerically-controlled oscillators configured to different output frequency if driven by the same reference oscillator.

An apparatus for detecting energy consumption in a local power supply system having at least one central line and a plurality of sublines branching from the central line and connected to consumers includes at least one detection unit for centrally detecting the individual energy consumptions of the individual consumers, the detection unit having an analog-to-digital converter detecting electric voltage on the central line. An analog input of the analog-to-digital converter is connected to the central line. The detection unit has a plurality of input channels, each input channel being coupled to a measuring transformer integrated into one of the sublines for measuring the flow of current through said subline. The detection unit is configured to successively sample the input channels and determine individual energy consumptions in each subline based on measured current flow through sublines and detected voltage on the central line.
