voltage error
In this study, an artificial neural network-based voltage compensator is proposed to reduce the voltage error between the reference and the actual voltages.
This architecture, however, exhibits a reference voltage error caused by resistor ladder loadings.
According to this behavior, the voltage error is only dependent on the current level for a given device.
Charge injection from the switch-control signal causes a voltage error at the analog output.
Current amplitudes were below 1,500 pA, resulting in a voltage error of 12 mV.
Experiments were rejected when, at the maximum peak current, the voltage error exceeded 5 mV after compensation of series resistance.
Experiments were rejected when the voltage error exceeded 5 mV after compensation of the series resistance.
Given the average series resistance of our electrodes, the maximal uncompensated voltage error was 5 mV for the largest currents studied.
In this case, the voltage error compensation causes vibration of the input current.
In this period no voltage error is introduced in the carrier signal, and conventional compensation methods could compensate for that error.
Only data from cells with uncompensated series resistance and current sufficiently small to give a voltage error of 5 mV were analyzed.
Only data from cells with series resistances and currents small enough to give a voltage error of less than 5 mV were analyzed.
Similarly, in the case of current commutation, the voltage error during the overlap-time of the forward IGBT depends on the load current direction.
Series resistance compensation limited the voltage error to less than 3 mV.
Series resistance could be adjusted to 90% or better and thus little voltage error occurred even for large command voltages.
Together with the 0.25% feedback resistors, the circuit provides less than 1% output-voltage error over temperature.
This cycle removes buffer amplifier, integrator and comparator offset voltage error terms from the conversion.
This method realizes that, from a certain current threshold level, the voltage error is a function of the current.
This effect is seen as a nonlinear voltage error modulation in phase with the phase current for low-magnitude currents.
The voltage error, VDC err, is input to a P controller trying to keep the DC voltage within tolerable limits.
