Selfcalibrated primary alternative current ratio standard

2012 Conference on Precision electromagnetic Measurements, 2012
Primary alternative current ratio standard, including 3 standard current transformers and precise comparator, used for comparison of the standard current transformers and for their selfcalibration is described. The results of the intercomparison of the intercomparison of the created standard with Russian Federation one are given.

A simple monolithic current-gain cell for large current ratios

International Journal of Electronics, 1980
A simple current-gain circuit is presented which generates large temperature insensitive current ratios accurately defined by small ratios of resistance and device area. Precision better than 1% and 100 ppm/°C is obtained in practice. A gain-bandwidth product of 1 GHz has been measured.

Log-ratio current for beam position monitoring

Conference Record of the 1991 IEEE Particle Accelerator Conference, 2002
The logarithmic ratio of the signal amplitudes from beam-position probe-electrodes provides a normalized real-time analog signal that is more linear in beam displacement than other signal-processing techniques for circular cross-section, beam-position monitors.

The ratio error of the overlapped-tube cryogenic current comparator

IEEE Transactions on Instrumentation and Measurement, 1990
Analytic expressions for the ratio uncertainty of the overlapped-tube cryogenic current comparator are derived for dimensioning the overlapped-tube comparator. Theoretical predictions agree reasonably well with experimental observations by H. Ramin (Arch. Elektrotech., vol.58, p.53, 1976).

A Self-Balancing Device for the Measurement of Ionization Current Ratios

The British Journal of Radiology, 1955
The accuracy of many ionization measurements on X-ray machines is limited by the inherent fluctuations, with time, of the output from X-ray generators. To overcome this difficulty, Kemp (1945, 1946) developed a very ingenious device which measures the ratio of two integrated dosage rates obtained from two condenser-type chambers in a common X-ray beam.

Practical Design Considerations for a Si IGBT + SiC MOSFET Hybrid Switch: Parasitic Interconnect Influences, Cost, and Current Ratio Optimization

IEEE transactions on power electronics, 2019
In this paper, a hybrid switch (HyS) consisting of a large current rated Si insulated-gate bipolar transistor (IGBT) device connected in parallel with a small current rated SiC MOSFET device (low SiC/Si current ratio below unity) is proposed for high ...

Accurate DC Current Ratio Measurements for Primary Currents up to 600 A

IEEE Transactions on Instrumentation and Measurement, 2015
A setup based on a direct current (dc) comparator, typically employed in high-current low-resistance calibrations, has been developed for the accurate calibration of dc current ratios for dc currents up to 600 A. For primary currents above 100 A, multiple turns of the primary conductor are made through the device under test. A full uncertainty analysis
