At National Institute of Metrological Research (INRIM), an automated setup to calibrate dc voltage generators, mainly top-level calibrators, from 1 mV to 1 kV has been developed.
The expanded uncertainties of the calibration of the 10 1 and 100 1 ratios are respectively 4.6 × 10−7 and 6.6 × 10−7, suitable to employ the divider in an automated measurement setup with a DMM and a DC voltage standard to calibrate DC voltage generators as top-level calibrators, widespread in secondary electrical laboratories.
Bias signals were applied through a signal line of the coplanar device using a DC voltage source, a signal generator, a function generator and a pulse generator for steady-state emission, time-resolved high-speed emission measurement, real-time optical communications, or pulsed light generation, respectively.
DC-DC converters allow DC sections with different DC voltage levels to be interconnected.
However, existing systems are using rectifying circuits to convert variable voltage and variable frequency output of electric generator into DC voltage and then use grid-tied inverter to connect to the power grid.
Three-phase diode bridge rectifier is used to convert the variable magnitude, variable frequency voltage at the induction generator terminal into DC voltage.
The high-voltage power supply Gamma High Voltage Research (Model number ES3OP-10W/DAM, USA) generated the DC voltage of 9 kV.
A DC voltage or a mixed DC-AC voltage from a signal generator (20 mHz Pulse/Function generator, model 628, Dynatech, Nevada) is applied in the cis side of the bilayer via Ag/AgCl electrode.
