Abstract

A double input DC-DC converter based on Zero-Voltage Transition technique enough to attract power from two distinct sources serving a joint dc-bus is projected. This converter belongs to higher-order family behaving as buck converter with one dc source and it also performs as both buck and boost converter with another source. Here the two sources either independently or concurrently deliver power to the consequent load with least ripple current is an important aspect of the suggested converter. This aspect is mainly needed for photo-voltaic applications. The main objective here is to realize the soft-transition by incorporating the ZVT cell into the double input DC-DC converter which allows to increase the efficiency by decreasing the switching losses and current/voltage stresses in the converter. The digital voltage controller for the converter is designed using SISO tool in MATLAB. Analysis of 24V, 96W converter is done through both experimental process and simulation.
