Abstract
A centralized digital controller design methodology is proposed for a two-input DC-DC converter. An hankel-norm based interaction analysis is developed to quantify the interaction of the controlling input and outputs of the proposed two-input dc-dc converter. The proposed converter is capable of feeding power to the common load either individually drawing from any one source or simultaneously drawing from both the sources. The load division on the two-input source is demonstrated through a two-loop control strategy. A digital current controller ensures load division in the input sources while the bus voltage regulation is achieved through a single-loop voltage-mode controller. A 24 V, 60 Watt converter performance is analyzed and compared with the experimental observations.
