This paper presents the development of an interleaved bidirectional DC-DC converter with single-phase high-frequency isolation associated with two different pulse width modulations (PWM), one for each power flow direction. The converter stages analysis, DC voltage gains expressions, and voltage/current stresses in CCM are presented. The proposed converter advantages are new modulation, the current ripple frequency and voltage in two ports is four times higher than the switching frequency, volume and weight reduction of passive elements, and balanced current distribution between the legs. Besides, the single-phase transformer that provides galvanic isolation between the DC bus and the battery or supercapacitor. An experimental prototype is implemented in the laboratory to validate the mathematical and theoretical analysis for both energy flow senses under the test conditions at converter-rated power 2.5kW, Low voltage side 180V, and high voltage side 380V.
