An Interleaved Boost Converter with LC Coupled Soft Switching

Novel full bridge DC-DC boost converters are mainly used in research applications, where the output voltage is measurably higher than the source voltage. We are researched in this project a comparison between two converter topologies of this type the standard zero voltage switching (ZVS) active clamp has topology and a new zeroed current switching (ZCS) topology. By using the interleaved approach this network topology not only decreases the current stress of the main circuit device but it also reduce the ripple of the input current and output voltage. However by establishing the common soft switching module, this soft switching interleaved converter can greatly reduce the size and cost. This topology has a characteristic that the operational analysis is not equivalent in D>50 % and D<50%. It is not the aforementioned interleaved boost converter, but it is two conventional boost converters working in the ac input source. This topology has a light weight and cost less. And this technique can be reduces the switching losses and improve the efficiency by ZVS technique, but it does not improve the turn-off switching losses by a ZCS technique. Our proposed topology has two operational conditions depending on the situation of the duty cycle. The design analysis is simulated using MATLAB Simulink model which illustrate the better performance of the converter
