Abstract


A new dc-dc converter consisting of one active switch (transistor), three diodes, two inductors and two capacitors is proposed. The new converter is theoretically analyzed in continuous conduction mode (CCM) operation, in which the converters are used in most applications. Then, the feasibility is studied using a simulation tool and a practical prototype. All these prove that the convertor operates as expected and that it has a second-order (quadratic) dc conversion ratio. Its applicability is related to conversion where a small step-down voltage is needed. Also current mode control can be easily implemented in this topology, when output current is of interest.
