ABSTRACT
The DC-DC converters are widely used in regulated switched-mode DC power supplies and DC motor drive applications. The input to these converters is often an unregulated DC voltage, which is obtained by rectifying the line voltage, and therefore it will fluctuate due to changes in the line voltage magnitude. Switched-mode DC-DC converters are used to convert the unregulated DC input to a controlled DC output at a desired voltage level [1].
