Description
Summary:Interleaved power converter topologies have received increasing attention in recent years for high performance applications. In this paper, a comprehensive multi-mode performance analysis is presented for interleaved boost converters operating over the entire duty ratio range (0 ≤ switch duty ratio ≤ 1) under the continuous conduction mode (CCM) and two discontinuous conduction modes (DCMs). With inductor coupling factor and converter loading as parameters, key performance indicators such as the dc voltage gain, input ripple current, inductor ripple current, and output ripple voltage are presented in a normalized form to aid the converter design process. Transitions among the CCM and two DCM modes are clearly defined for the entire switch duty ratio range. Advantages of DCM operation such as reduced switching loss at the expense of undesired ringing are discussed. The comprehensive multi-mode analysis has been experimentally verified using a 250 W, 70 kHz prototype converter unit.
