Abstract
This paper presents a new auto-tuning method for the wide input voltage range digital control buck-boost dc-dc converter. This buck-boost dc-dc converter is used with wide input voltage and a suitable proportional gain and bias value are changing against the input voltage of the converter. The gain and bias value are changed suitably in real time with digital control. As simulation results, it is revealed that both the static characteristics and dynamic characteristic can be improved. Especially, the steady-state error is improved from 653 mV to 80 mV and 296 mV to 50 mV, respectively.
