A multi-port multiple-output topology is presented to efficiently interface independent dc loads with diverse dc sources in electric vehicles. The main characteristics of this new circuit topology are, namely, ability to convert power from any number of energy resources to any number of loads, to supply output voltages that are greater than maximum input voltage or lower than minimum input voltage, avoiding bulky transformer, and minimum possible storage elements (a single inductor). Different operation modes of the circuit are characterized, analyzed, and verified by detailed switch-level simulation for all operational modes.
