Capacitor Commutation Method for MVDC Hybrid Circuit Breakers
Designs, 2021 The medium voltage DC (MVDC) type system can connect multiple terminals to a common MVDC bus, so it is possible to connect several renewable DC power sources to the common MVDC bus, but a DC circuit breaker is needed to isolate short circuit accidents ...

Analysis and implementation of hybrid switching [PDF]
Proceedings of the 22nd annual international symposium on Computer architecture - ISCA '95, 1995 The switching scheme of a point-to-point network determines how packets flow through each node, and is a primary element in determining the network's performance. In this paper, we present and evaluate a new switching scheme called hybrid switching.

Power switching in hybrid coherent couplers [PDF]
IEEE Journal of Quantum Electronics, 1997 We report on a theoretical and numerical investigation of the switching of power in new hybrid models of nonlinear coherent couplers consisting of optical slab waveguides with various orders of nonlinearity. The first model consists of two guides with second-order instead of the usual third-order susceptibilities as typified by the Jensen coupler. This

Improving HybrID: How to best combine indirect and direct encoding in evolutionary algorithms. [PDF]
PLoS ONE, 2017 Many challenging engineering problems are regular, meaning solutions to one part of a problem can be reused to solve other parts. Evolutionary algorithms with indirect encoding perform better on regular problems because they reuse genomic information to ...
