Scalable Marine Bus-Tie Switch for Switchboard Interconnections

Drazen Dujic, Gabriele Ulissi

DC power distribution systems in marine applications are in the process of being established as the preferred solution for shipboard power distribution systems. This paper presents a bus-tie switch topology for the protection of such systems. The device is ...

IGCT Based Solid State Resonant Conversion

Dragan Stamenkovic

Driven by the environmental changes, penetration of renewables and the need for more flexible power grid, DC is reemerging as a basis for future power networks. Already established in the area of HVDC for very long distance transmission, more and more atte ...

The Upper Bound of the Speed of Propagation of Waves along a Transmission Line

Farhad Rachidi-Haeri, Marcos Rubinstein

According to theory, once certain conditions are fulfilled, current and voltage pulses propagate along ideal transmission lines with the speed of light. One can reach such a conclusion only when the conductors are assumed to be perfectly conducting, which ...

Grid-Supporting Battery Energy Storage Systems in Islanded Microgrids: A Data-Driven Control Approach

Alireza Karimi, Reza Razzaghi, Behrooz Bahrani

Islanded microgrids have low real and reactive power generation capacity and low synchronous inertia. This makes them susceptible to large frequency and voltage deviations caused by switching of large loads or equipment failures. These events deteriorate p ...

Protection Coordination in Marine DC Power Distribution Networks

Seongil Kim

The increasing penetration of renewable energy sources, energy storage systems (ESSs), and DC loads has opened the door to DC technology to pave its way into future grids. The shift has been more obvious in the marine domain supported by track records of i ...

Bosonic superfluid transport in a quantum point contact

Jean-Philippe Brantut

We present a microscopic theory of heat and particle transport of an interacting, low-temperature Bose- Einstein condensate in a quantum point contact.We show that, in contrast to charged, fermionic superconductors, bosonic systems feature tunneling proces ...

A Low-Power 9-Bit 222 MS/s Asynchronous SAR ADC in 65 nm CMOS

Yusuf Leblebici, Firat Çelik, Ayça Akkaya

This paper presents a 9-bit 222 MS/s low-power asynchronous single-bit/cycle successive approximation register (SAR) ADC. The SAR ADC combines techniques such as asynchronous clocking, binary-weighted custom-designed capacitive DAC with small unit capacito ...
