Improvement in Transient Response of Fast P Control DC-DC Converter with Static Model
MetadataShow full item record
The purpose of this paper is to propose the digital control method that is comprised of the fast P control and model control for an improvement of the transient response of the dc-dc converter. The electronic devices are required the operation in the standby mode and the quick return to the active mode. The fast transient response of the dc-dc converter in such condition is important. In this paper, the fast P control is combined with the model control. Therefore, the transient response in such situation is improved because the operating point is optimized according to the load current. From the results, in the case of the load step from DCM to CCM, the undershoot and the convergence time are improved by about 80%.
