1. Modeling, Control and Protection of Low-Voltage DC Microgrids
Sammanfattning : Current trends in electric power consumption indicate an increasing use of dc in end-user equipment, such as computers and other electronic appliances used in households and offices. With a dc power system, ac/dc conversion within these loads can be avoided, and losses reduced. LÄS MER
2. Low-Power Low-Jitter Clock Generation and Distribution
Sammanfattning : Today’s microprocessors with millions of transistors perform high-complexitycomputing at multi-gigahertz clock frequencies. Clock generation and clockdistribution are crucial tasks which determine the overall performance of amicroprocessor. LÄS MER
3. Ultra-Low Power InAs/AlSb HEMTs for Cryogenic Low-Noise Applications
Sammanfattning : The InAs/AlSb high electron mobility transistor (HEMT) is an emerging microwave device technology for ultra-low power and low noise applications. Due to the low bandgap (0. LÄS MER
4. Waste-heat Recovery Using Thermoelectricity and Silicon Carbide Power Electronics
Sammanfattning : Energy consumption in the world has increased continuously due to a growing population and increased energy consumption per capita. Moreover, the largest part of consumed energy still comes from fossil sources which in 2016 was more than 130 PWh. LÄS MER
5. Low-Power HEMT LNAs for Quantum Computing
Sammanfattning : The rapid development of quantum computing technology predicts much more qubits to handle in the detection, readout, and amplification of qubits than in today's system. Due to the limited cooling capability of the dilution refrigerator, the current low-noise amplifiers (LNAs) are in need of ten to hundred times reduced dc power consumption yet with lowest noise temperature at qubit readout frequencies, typcially 4-12 GHz.
