AB A new non-isolated DC-DC converter with non-inverting output and buck-boost operation, named Magnetically CoupledBuck-Boost Bidirectional converter (MCB³), is presented in this paper. The MCB³ passive components arrangement connects the inputand output ports getting an equivalent behavior to that of the Dual Active Bridge (DAB) converter, but in a non-isolated topology. Thisequivalency allows applying Triple Phase Shift (TPS) modulation to MCB³. TPS is known to minimize conduction losses and to achievesoft-switching at any load in the DAB converter. Throughout the paper, the features of the DAB converter are used as a reference to showthe main features of the proposed converter. Moreover, other modulation strategies based on TPS modulation are used in MCB³ tooperate within the minimum losses path.The multiple operation modes found on the MCB³ under TPS modulation are identified,classified, and used to find the operating points that minimize the switching and conduction losses over the power range. The analysis isshown for the boost mode that is the worst-case design. MCB³ and DAB topologies are designed and simulated for the same specificationto validate the theoretical study. Finally, experimental measurements on 460W-prototypes for both topologies corroborate the equivalentoperation and the main features of the MCB³.
