A new Zero-Voltage Transition based two input DC-DC converter sufficient to draw power from two distinct sources feeding a common dc-bus is presented in this paper. This converter belongs to higher-order family and behaves as buck converter for one dc source also it acts as both buck and boost converter with the other source. The significant feature of the proposed converter is that both the sources either singly or simultaneously supply power to the subsequent load at minimal ripple current. This feature is particularly attractive for photo-voltaic power processing applications. The main objective here is to realize the soft-switching by integrating the ZVT cell into the two input DC-DC converter enabling to improve the efficiency by reducing the switching losses in the converter. The digital voltage-mode controller for the converter is designed using SISO tool in MATLAB. A 24V, 96W converter is analyzed and compared with the simulation results.
