Abstract: This paper proposes a new modified interleaved buck converter which can be used where the operating duty cycle is required below 50%. The switching losses and the stress of the switches has been reduced with the IBC and hence the buck conversion efficiency also is increased to 93.3%. The output current ripple is found to be very small with the modified IBC. The operating principles and different modes of operations of the modified IBC are explained in this paper.
Keywords: Buck converter, Interleaved, low switching losses.
