A Generalized Modular Multilevel Current Source Inverter
This paper proposes a novel topology of multilevel current source inverter which is suitable to apply in low/medium voltage. The proposed topology is capable of producing desirable bidirectional output current levels. Furthermore, it can employ symmetrical DC current sources as well as asymmetrical ones which is a significant advantage. Asymmetrical mode makes it possible to generate a great nu...
متن کاملHigh-current, High-duty-factor Experiments with the H Ion Source for the Spallation Neutron Source
The ion source for the 1 MW Spallation Neutron Source (SNS) is required to provide 35 mA of H beam current at 6% duty factor (1 ms pulses at 60 Hz) with a normalized rms emittance less than 0.15 π mm mrad. The H beam will be accelerated to 65 keV and matched into a 2.5 MeV RFQ. The ion source is expected to ultimately produce 70 mA of H at 6% duty factor when the SNS is upgraded to 2 MW of powe...
متن کاملImproved current-source sizing for high-speed high-accuracy current steering D/A converters
This paper describes a design methodology for the basic current source cell circuit of high-speed high-accuracy current steering DIA conveners taking into account mismatching in all the transistors of the cell. Previous works consider arbitrary safety margins in the sizing process. The presented approach allows a more accurale selection of the optimal design point. The design methodology is ill...
متن کاملModeling of high-current source-gated transistors in amorphous silicon
Compared with the field-effect transistor, the source-gated transistor has a much lower saturation voltage and higher output impedance. These features are investigated using computer modeling for amorphous silicon transistors operated at high currents when source barriers are low. In particular, it is shown that low saturation voltages are maintained at high current and are insensitive to sourc...
متن کاملNew progress of high current gasdynamic ion source (invited).
The experimental and theoretical research carried out at the Institute of Applied Physics resulted in development of a new type of electron cyclotron resonance ion sources (ECRISs)-the gasdynamic ECRIS. The gasdynamic ECRIS features a confinement mechanism in a magnetic trap that is different from Geller's ECRIS confinement, i.e., the quasi-gasdynamic one similar to that in fusion mirror traps....
