Quadratic step-down dc-dc converters based on reduced redundant power processing approach Article uri icon

abstract

  • In the technical literature the interconnection of switching converters to increase power handling capabilities on dc applications has been widely reported. This study presents a family of switching step-down dc-dc converters based on the principle of reduced redundant power processing (R2P2). This states that the power transfer from input port to output port on interconnected converters can be reduced, if a non-cascading connection is used. As shown in this study, the principle R2P2 is useful for developing new converters. The resulting converters are formed by a pair of L-C networks and a pair of active switches, also they have wide conversion ratios and quadratic dependence with respect to the duty ratio. In this study, the voltage conversion ratios and steady-state operating conditions are derived for the proposed converters, which are verified by experimental results. © The Institution of Engineering and Technology 2013.
