This paper describes a circuit, which generates temperature-independent bias currents. In this paper, low-temperature coefficient reference is presented. The circuit firstly employed to generate current with temperature compensation, then combining the opposite characteristic curve minimize variation of temperature. proposed has been design by 0.18μm CMOS technology process and using computer simulation evaluate thermal drift current. used provide stable for controlled oscillator(CCO). CCO...
Power electronic equipment regulated by International Thermonuclear Experimental Reactor (ITER) must pass the relevant steady-state magnetic field immunity test. The main body of test is generator coil. Through mathematical derivation in this article, calculation formulas four-coil configuration under ideal and actual models are obtained. traditional method performance compared with general formula model. A global parameter optimization based on Lagrange Multiplier Karush–Kuhn–Tucker (KKT)...
This paper describes a circuit, which generates low temperature-dependent bias currents. In this paper, temperature coefficient reference is presented. The circuit firstly employed to generate current with compensation, then, supply the controlled ring oscillator (CCO). Because of oscillation frequency CCO proportional temperature, designed be inversely compensate variation CCO. There are four different compensation has been completed, they 10MHz, 20MHz, 30MHz and 40MHz respectively....
The support frame is an important part of International Thermonuclear Experimental Reactor (ITER) poloidal field (PF) converter system. It mainly used for dc busbars and disconnector switch support. This article introduces a seismic analysis three types frame. In order to evaluate the response structure under specific excitation, method based on spectrum adopted in this article. design earthquake level one (SL-1) with damping factor 2% as well 4% provided by ITER applied load. define maximum...
Abstract Medical image generation from diagnostic report has important research significance for medical‐aided diagnosis. This can improve the diagnosis speed and accuracy of doctors effectively save storage resources hospitals. The made significant progress in field natural images, but rarely used medical images. images have higher requirements quality. In this paper, a method based on attention mechanism content preservation loss to quality is proposed. model consists three stages, each...
The poloidal field (PF) converter units (CUs) with the four-quadrant operation and circulating current capability is to supply power International Thermonuclear Experimental Reactor (ITER) superconducting magnets. To ensure PF system safety reliability for operation, distance of transformer installation calculated studied. electromagnetic installed equipment analyzed discussed determine layout design equipment. When operates at steady-state rated 55 kA, heat dissipation cooling water system....
this paper proposes an alternative analytical algorithm for a general nonlinear multi-objective optimization problem. Rather than employing the vertical coordinate system as in existing algorithms, our adopts parallel system. This new can guarantee to obtain exact Pareto optimum, which is independent of relative scales objective functions and successful producing representative points set. The composition these properties missing from popular methods like weighted sum or ε-constraints....
The short-circuit protection device (snubber or crowbar) of high-voltage power supply can absorb bypass the energy fed by when klystron sparks and protects klystron. reliability test snubber crowbar becomes an urgent demand. This article presents a simple method to crowbar, in which thin wire is adopted replace simulate its sparking characteristics. When occurs, will fuse if it over 6 J effect included. mainly focuses on how design such for burn test. At first, theoretical model proposed...
In order to analyze the induced current of component under ITER PF converter bridge, bedframe bridge has been taken for an example explain this process calculation in paper. Firstly, a numerical analysis method suggested calculate based on actually physical model. Then, and voltage achieved according method. Finally, experiment results verify validity proposed
According to the ITER requirement, availability of poloidal field (PF) coil power supply system must be 98.3% during life cycle ITER. In order meet this Reliability, Availability, Maintainability, and Inspectability (RAMI) analysis has been applied for analyzing reliability PF system. First, function analyses, which are described using Integration Definition Function–language Ø or IDEFØ model performed. Second, failure mode effect criticality analyses used calculate risk level, present...
