Regulators and converters

Very often different circuits and unit requires different voltage and current source from each other, to supply such different for each circuit we use a converter to do so. convertor is the general name for system in which has input connection for some kind of system, and it provide output connection to supply a system, convertor can be isolated or not isolated, an isolated converter is required when we want to provide a safety requirement between systems, for example, if a circuit used to monitor the HV system we want to have an isolated supply for it since, in case of some failure we do not want to have high voltage in the low voltage system! isolated system provide at the output side both positive and negative terminals and usually have a transformer to create a galvanic isolation, non-isolated converter usually share the negative output terminal with the same negative terminal of the input.

Regulator is system (under specific terms) provides stable output nether the less the load size. regulators usually come in a single chip design that can be function both as regulator and convertor, for example the 7805 component.

Regulators and converters are key components for every DC-DC unit, knowing to work with them is extremely important for minimizing the depending on off shelf dc-dc units, saving costs and space.
