Understanding the three and four-leg inverter Space Vector [PDF]
, 2016 This paper shows a new point of view of the classical voltage space vectors and its implications on three and four-leg converters. It is easy to find in the literature, authors using bi-dimensional and threedimensional representations of the converter ...

Quantum phases of a frustrated four-leg spin tube [PDF]
, 2013 We study the ground state phase diagram of a frustrated spin-1/2 four-leg tube. Using a variety of complementary techniques, namely density matrix renormalization group, exact diagonalization, Schwinger boson mean field theory, quantum Monte-Carlo and ...

The dimer-RVB State of the Four-Leg Heisenberg Ladder: Interference among Resonances [PDF]
, 1999 We study the ground state of the 4-leg spin ladder using a dimer-RVB ansatz and the Lanczos method. Besides the well known resonance mechanism between valence bond configurations we find novel interference effects among nearby resonances.Comment: 4 pages,

Reduced-Sensors-Based Predictive Controller for LC Filtered Four-Leg Inverters
IEEE Open Journal of Industry Applications, 2021 The high number ofsensors, ten in total, required by the traditional finite control set model predictive control (FCS-MPC) strategy of a four-leg inverter with LC output filter increases the complexity and cost of the system and limits the practical ...

Enhanced Torque Control of a PMSM Supplied by a Four-Leg Voltage Source Inverter Using the Third Harmonic [PDF]
, 2008 This paper investigates an electrical drive composed of a four-leg voltage source inverter and a three-phase starconnected surface permanent magnet synchronous machine with concentrated windings. The inverter fourth leg is clamped to the neutral point of

New design procedure for four-leg channelized intersections
Građevinar, 2017 The design and possible simplifications of four-leg channelized intersections are analysed in the paper. The research resulted in a new simpler approach in which all intersection elements are properly formed from the very beginning, so that the need for ...

Understanding roundabout safety through the application of advanced econometric techniques
International Journal of Transportation Science and Technology, 2020 Intersections present a significant safety concern, as such in an effort to reduce the more serious injuries occurring at or near intersections, many jurisdictions have turned to implementing roundabouts.

A new space-vector-modulation algorithm for a three-level four-leg NPC inverter [PDF]
, 2016 For power conversion systems interfaced to 4-wire supplies, four-leg converters have become a standard solution. A four-leg converter allows good compensation of zero-sequence harmonics and full utilization of the dc-link voltage.

Excitations in a four leg antiferromagnetic Heisenberg spin tube [PDF]
, 2008 Inelastic neutron scattering is used to investigate magnetic excitations in the quasi one dimensional quantum spin liquid system Cu2Cl4 D8C4SO2. Contrary to previously conjectured models that relied on bond alternating nearest neighbor interactions ...
