DIRECT CURRENT DIRECT CURRENT CONVERSION

Dc - dc converters are widely used in dc power supplies and in some applications of dc motor drive. Often, the input to this type of converters is a dc non-regulated voltage, obtained by rectifying the mains voltage and, consequently, fluctuating due to changes in the amplitude of the line voltage.

The result of the conversion is a controlled dc output at the desired voltage level.
