This brief blog post explains how a DC-DC Converter can be used to adjust power supply in various electronic configurations.
There’s always something
powering an electronic device, be it a battery or some other power source such
as a circuit. The problem is, however, that power is actually not always
flowing consistently. Sometimes it dips or surges. Special tools manage the
situation well.
The engineers who design
gear must be aware of this. It’s likely they are, though. They’ll be the first
ones to suggest using AC-DC converters, a step-down AC, a step-up AC, or some
other similar module. A variable power supply requires such adjustments.
For voltage adjustments,
one may employ the use of a potentiometer. To adjust the output to the right
level, a device may be equipped with an adjustable voltage regulator with line
regulation and load regulation.
The capacitor C3 bypasses
the pin of a voltage regulator to ground, to improve the ripple rejection
capability. Diodes are used to protect the regulator from excess that flows
through if any voltage source is connected across the output terminals of the
regulator.
The adjustable high-voltage power supply
is an integrated circuit that supplies the constant and controlled output
voltage no matter if there are changes in input voltage.
