Abstract :
This paper presents a new digital control buck-boost dc-dc converter with bias model to improve dynamic characteristics. The buck- boost converter needs to respond appropriately to changing input voltage and load change with wide input voltage. This approach makes adjustment to the bias value by input voltage and output current. As a result, it is revealed that not only the dynamic characteristics but also static characteristics can be improved and it is effective for wide range input voltage.
