Abstract

This study proposes a new interleaved pulse width modulation boost converter that uses only one auxiliary switch in its structure to create soft-switching condition for all semiconductor elements. This way leads that the proposed converter has a simpler structure in comparison with other similar interleaved topologies. Moreover, the auxiliary circuit is not located in the main power path from input to the output. So, the current rate of the elements in the auxiliary circuit is very low. Due to soft-switching condition for all semiconductor elements, the proposed topology has low power losses and high efficiency. The efficiency of the converter is 97.6% at full load range. Besides, using the interleaved structure in the proposed converter leads to lower current stresses on the circuit elements. A 120 W prototype of the proposed converter is implemented. The experimental results confirm the aforementioned advantages of the proposed converter such as high efficiency in comparison with other similar topologies.
