A New ZCT Interleaved High Step-up Converter

In this study, an interleaved high step-up converter with two lossless snubbers has been presented, so that the snubber provides conditions of zero current switching for main switches and this converter has no extra switch. In contrast, snubbers energy is transmitted to the output. In addition, all converter switches have a grounded source, and as a result, there is no need for an isolated drive circuit. The proposed converter has been completely analyzed and to prove the theoretical analysis of the circuit, a sample of it has been simulated in PSpice software and an 80-watt prototype of it has been fabricated.
