Analog circuits such as linear voltage regulators are very sensitive to electromagnetic interferences which induce voltage offset on their outputs. In harsh environments, the aging of this component can be accelerated and could lead to an increase of the effect of electromagnetic interferences. This paper proposes an original study about the drift of the susceptibility level of a low dropout voltage...
This paper presents a summary of the most important characteristics of wind turbine generators applied in modern wind power plants. Various wind turbine generator designs, based on classification by machine type and speed control capabilities, are discussed along with their operational characteristics, voltage, reactive power, or power factor control capabilities, voltage ride-through characteristics,...
Proper insulation coordination is critical to achieving expected life from wind plant equipment. The collector systems of large wind plants require the application of surge arresters to protect the equipment insulation from transient overvoltages. The application of surge arresters is constrained by maximum operating and temporary overvoltage levels. This paper provides a tutorial description of the...
This technical paper provides the basic guidelines for the application of reactive compensation systems to be used as part of a wind power plant. A brief history of wind plant reactive compensation system is discussed, then the fundamental needs of why reactive compensation is required. The paper will then provide some alternatives for reactive compensation, how to size the reactive compensation,...
We present in this paper a novel indoor blimp that is propelled by a propulsion technology that uses no moving mechanical parts and thus is noiseless and vibration free. In our prior work reported at IEEE/ASME AIM 2007, we demonstrated several prototype propulsive units (with asymmetric capacitor configurations) that lift themselves into air. Using these basic propulsive units (“Ionic Flyers”), we...
Technology scaling data are presented based on 65 nm, 45 nm, and the 32 nm high-K, metal gate process. Thin oxide NFET parasitic bipolar snapback and gate dielectrics breakdown voltages decrease to 3.2V and 3.6V, respectively. The top concern is to achieve adequate voltage clamping at I/O pads. Continuous improvement in ESD device failure currents per area is found. Vertical metal wiring schemes are...
This paper introduces technologies of the dimmable electronic ballast for metal-halide lamps (MHLs). The topology structure of the ballast includes AC/DC converter, DC/DC converter, DC/AC inverter, even dimming and protection functions that can be applied in many kinds of MHLs. The output power of the ballast is stably by means of feedback of the current from the lamp. Especially, the light intensity...
