Generally interleavedbuck converters are hard switched and hence the switching losses are high. Here an interleaved zero-current transition (ZCT) buck converter where two sets of switches are operating out-of-phase and share the load power equally is introduced. Turn-on transitions at zero current helps to reduce switching losses and a significant reduction of the losses associated with diode reverse recovery are accomplished through addition of two small inductors. The simulation of different interleaved buck converters is completed with MATLAB. This paper also presents a comparison of switching loss and conduction loss of interleaved hard switched buck converter, interleaved zero current transition buck converter, and interleaved zero current transition three level buck converter. The loss analysis of different interleaved buck converters is completed with the help of thermal modules in Powersim.
