Generalized measure of quantum synchronization [PDF]

Physical Review Research, 2020
We present a generalized information-theoretic measure of synchronization in quantum systems. This measure is applicable to dynamics of anharmonic oscillators, few-level atoms, and coupled oscillator networks. Furthermore, the new measure allows us to discuss synchronization of disparate physical systems such as coupled hybrid quantum systems and ...

A cryogenic dc-dc power converter for a 100kW synchronous HTS generator at liquid nitrogen temperatures

, 2012
A dc-dc converter has been developed for retrofitting inside the vacuum space of the HTS rotor of a synchronous generator. The heavy copper sections of the current leads used for energising the HTS field winding were replaced by cryogenic power ...

Transient Analysis of Microgrids With Parallel Synchronous Generators and Virtual Synchronous Generators

IEEE Transactions on Energy Conversion, 2020
In recent years, the increasing penetration of distributed generation in microgrids challenges the control and coordination of energy resources. Especially in microgrids with virtual synchronous generator (VSG)-controlled converters and conventional synchronous generators (SG), the inherent inertia difference (i.e., the VSG and SG) results in a poor ...
