Two-Loop Controlled SEPIC - Boost Converter For Power Management

The two-input dc-to-dc converter is a novel technique for power management in dc grid. The proposed two-input converter is made with a combination of SEPIC type PCSC along with a boost converter. The two-loop controlling strategy is used for the distribution of load on an integrated two input SEPIC PCSC – Boost Converter for DC-to-DC power conversion system. The discrete time model is applied to viable combination of input and output quantities, to control source current and load voltage, for getting ideal load distribution to input. The proposed paper deal with the application of the RGA theory for the better understanding of control loop interaction and the choice of input and output pairs for power management.
