    Abstract : The urban and rural energy systems are undergoing modernization. This modernization is motivated by the need to increase sustainability in both systems. Some characteristics of this modernization include electrification of industries, transports, and heating and cooling loads. READ MORE

  5. 3. Frequency Reconfigurable and Linear Power Amplifiers Based on Doherty and Varactor Load Modulation Techniques

    Author : William Hallberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gallium nitride GaN ; wideband; Class-J; linear; microwave; radio frequency RF ; Doherty; broadband; AM AM; silicon carbide SiC ; bandwidth; power amplifier PA ; AM PM; varactor; dynamic load modulation DLM ; fifth generation mobile networks 5G ; energy efficiency;

    Abstract : In future mobile communication networks, there will be a shift towards higher carrier frequencies and highly integrated multiple antenna systems. The system performance will largely depend on the available RF hardware. As such, RF power amplifiers (PAs) with improved efficiency, linearity, and bandwidth are needed. READ MORE

  6. 4. System Studies and Simulations of Distributed Photovoltaics in Sweden

    Author : Joakim Widén; Ewa Wäckelgård; Brian Norton; Uppsala universitet; []

    Abstract : Grid-connected photovoltaic (PV) capacity is increasing worldwide, mainly due to extensive subsidy schemes for renewable electricity generation. A majority of newly installed systems are distributed small-scale systems located in distribution grids, often at residential customers. READ MORE

  7. 5. An impedance approach to passive-active vibration control

    Author : Jonas Svensson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hybrid passive-active vibration control; Active control; Euler- Bernoulli theory.; Impedance matching;

    Abstract : The complementary advantages of active and passive vibration control have motivated research concerning hybrid configurations. Previous studies have mainly focused on active constrained layers (ACL). However, investigations pointing towards suboptimal performance of ACL have made it interesting to investigate other solutions. READ MORE
