DC DC Converters

A DC-DC converter is an electrical device used to convert a power source from one voltage level to another. It is a form of electronic switching system, and it can be used to convert high or low voltage inputs into other kinds of voltage outputs. DC-DC converters can be used to convert current from direct current (DC) to alternating current (AC) or to control the voltage that is applied to an electrical device.
