A two-input fourth-order integrated (TIFOI) dc-dc converter regulates dc-bus voltage and low voltage source current with two switching devices and four energy storage elements. Each switch duty control signal in TIFOI converter system will affect the two output variables causing interactions. These interactions must be measured for proper controller structure selection. Interactions measurements may...
A participation matrix based interaction analysis is established for a two-input DC-DC converter and then a diagonal controller is designed. The control-loop interactions are estimated and then suitable controlling input-output pairs have been identified. By performing state-space analysis various useful transfer functions are obtained and transfer function matrix is form ulated, which is useful to...
A gramian based digital controller design is proposed for a two-input DC-DC converter suitable to draw power from two different dc sources feeding a common dc-bus is presented in this paper. The proposed converter is simple and it belongs to sixth-order family performing bucking as well as boosting features. The salient features of this converter are that both the sources either individually or simultaneously...
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...
A new two-input multi-port DC-DC converter suitable to draw power from two different dc sources, sources can be either dc or photovoltaic source, and then feeding a common dc-bus is proposed in this paper. This multi-port converter consists of two-switching devices, two diodes and four energy storage elements. Both bucking as well as buck-boost features are integrated within the single converter structure...
A new two-input DC-DC converter suitable to draw power from two different dc sources feeding a common dc-bus is presented in this paper. This is a two-switch converter belongs to sixth-order family and performs bucking operation for one dc source while it allows both bucking as well as boosting feature with the second source. The salient feature of the proposed converter is that both the sources either...
