Control and performance of a zero-current-switched three-phase inverter equipped with resonant circuits on the AC-side [PDF]

open access: yes, 1996
This paper presents a zero-current-switched voltage-fed inverter equipped with resonant circuits on the AC side. The current flowing through a switching device, i.e., an IGBT is a sum of the load current and the resonant current.

Phase Diffusion in Single-Walled Carbon Nanotube Josephson Transistors [PDF]

open access: yes, 2007
We investigate electronic transport in Josephson junctions formed by single-walled carbon nanotubes coupled to superconducting electrodes. We observe enhanced zero-bias conductance (up to 10e^2/h) and pronounced sub-harmonic gap structures in ...

Zero-Voltage and Zero-Current Switching Converters

open access: yesInternational Journal of Computer Applications, 2010
This paper deals with the simulation of a PWM three-level (3L) & five level (5L) converters. The modulation strategies can be classified into two kinds according to the turn-off sequence of the two switches of the pair of switches. The concept of the leading switches and the lagging switches is introduced to realize softswitching for PWM 3L and 5L ...
