4. ABSTRACT
Symmetric multiphase dc–dc converters are widely used in power electronics, as they
enable the processing of high power through splitting the overall load-current into multiple phases.
Distributing the processed power symmetrically between the phases and performing ripple
minimization through interleaving is well understood. However, in recent applications such as
maximum power point tracking for solar photovoltaic, converters are forced to operate under
asymmetric conditions, due to differences in the sources or loads of each converter. This study
presents a control technique, based on harmonic elimination, that allows for ripple minimization
under asymmetric conditions. The mathematical derivations are outlined and simulations are used to
evaluate the performance of the proposed technique. Measurements taken from an experimental
prototype, consisting of three dc–dc buck converters, demonstrate significant improvements in ripple
reduction over conventional interleaving techniques. When the multiphase converter is operated at
the optimum asymmetric phase-shift found through the techniques presented here, a more than 3x
reduction in net current ripple is observed under realistic operating conditions. Additionally, the
undesirable first harmonic ripple component is reduced by 14.8 dB with the proposed technique.
