Abstract
In this paper, a new interleaved buck converter with soft-switching is investigated. The soft-switching condition, zero voltage zero current switching (ZVZCS) of IGBTs during turn-on is obtained with the help of a soft-switching cell that includes active and passive devices that is incorporated in the interleaved buck converter (IBC). The presence of the soft-switching cell reduces the switching losses and improves the overall efficiency. The IGBTs in the converter achieved ZVZCS turn on operations, while converter is operated under both light and heavy loads. The principles of operation and theoretical aspects of the proposed converter system 400 V / 110 V / 2.5 kW are verified with simulation analysis.
