Abstract :

A triple-buck converter with zero voltage transient is presented in this paper. The proposed structure is formed by three parallel buck converter to increase the reliability which is utilized three interleaved inductors for connecting the stages to reduce the losses caused by hard switching. The zero voltage transistor is also performed by resonance between the parasitic capacitance of the power switches and the equivalent inductor seen from each capacitor. The proposed circuit analysis has been performed in different operating modes. The proposed Buck converter is simulated in the Matlab/Simulink environment. The simulation results prove that the switching losses as well as the loss of diodes can be reduced by zero voltage switching of the power switches and designed high-performance converter. The simulation results show that the output reaches its final value of 40 V after 0.6 ms and the output voltage variations is 0.5 V the output ripple is achieved 1.25%.
