A comprehensive and unified analysis is presented for the discontinuous conduction/current mode operation of dual interleaved buck and boost converters with an interphase transformer or coupled inductors. By exploiting the symmetry in the current waveforms between the buck and boost modes of operation, detailed operating maps are derived showing the seven separate discontinuous operating patterns in each circuit. Boundary conditions and overall conversion characteristics are presented along with validation results from simulations and measurements on high‐power prototypes.
