  2. 1. Design and Optimization Considerations of Medium-Frequency Power Transformers in High-Power DC-DC Applications

    Author : Amin Bahmani; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nanocrystalline-Magnetic Core; High-Power Isolated DC-DC Converter; Solid-State Transformers; Leakage Inductance; Isolation Requirements; Medium-Frequency Power Transformer;

    Abstract : Recently, power electronic converters are considered as one of the enabling technologies that can address many technical challenges in future power grids from the generation phase to the transmission and consequently distribution at different voltage levels. In contrast to the medium-power converters (5 to 100 kW) which have beenessentially investigated by the automotive and traction applications, megawatt and medium-voltage range isolated converters with a several kilohertz isolation stage,also called solid-state transformers (SST), are still in an expansive research phase.

  4. 2. Power Electronics for Mitigation of Voltage Sags and Improved Control of AC Power Systems

    Author : Marcio Magalhães de Oliveira; KTH; []
    Keywords : power electronics; power quality; voltage sags; voltage-source converters; Custom Power; FACTS; real-time simulations; solid-state devices;

    Abstract : The thesis deals with the application of compensators andswitches based on power electronics in AC transmission anddistribution systems. The objective of the studieddevices/equipment is the power flow and voltage control intransmission systems and the mitigation of voltage sags andmomentary interruptions to critical loads in distributionsystems.

  5. 3. Design and Control of Long-Pulse High-Power Klystron Modulators

    Author : Max Collins; Industriell elektroteknik och automation; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The European Spallation Source (ESS) is an under-construction material science research facility in Lund, Sweden, and will upon completion host the most powerful superconducting linear accelerator (linac) in the world. The ESS linac is powered by klystron modulators required to deliver long high-power pulses (pulse amplitude 115 kV/100 A, pulse length 3. READ MORE
