Kiruba.T , Santhi.M

In this paper, an interleaved boost converter with zero-voltage transition and zero-current transition characteristics is proposed. The interleaved approach reduces the ripple of the input current and output voltage. The active snubber cell provides main switch to turn ON with zero-voltage transition (ZVT) and to turn OFF with zero-current transition (ZCT). All semiconductor devices operate with soft switching. There is no additional voltage stress across the main and auxiliary components. The proposed converter has simple structure, minimum number of components, and ease of control. The operating principle and detailed steady-state analysis of the converter are given. The proposed converter is simulated using MATLAB/SIMULINK
