In this case, the voltage divider R1-R2 compensates the voltage variations to some extent.

According to the relations, given above, this implies also small current and voltage variations.

The most significant variation would be due to voltage variations.

This was due to the high cost of a regulating element, and the relative insensitivity of the power output stage to voltage variations.

The intermediate DC circuit's voltage variation is automatically taken into account in the algorithm (in voltage integration).

In double conversion mode the UPS can adjust for voltage variations without having to use battery power, can filter out line noise and control frequency.

In the West, the atmospheric administration said, utilities recorded voltage variations of up to 5 percent.

Hence the output voltage, within the design limits, remains constant over a wide range of current and input voltage variations.

Some puzzling variations in readings were conceivably due to voltage variations and an experiment was performed to test this.

It would be possible to make a correction for voltage variations on the basis of these figures.
