A single-stage current-fed DC-DC converter structure and control strategy is described which allows simultaneous control of both output voltage and current flowing in the input inductor. This solution is well suited for high-power-density applications, since it results in very reduced converter size and power loss. Moreover, a very fast control-to-output response is obtained, together with stable operation even for large load and reference variations. Static and dynamic converter performance is investigated, and design criteria are given. Experimental results obtained on a prototype are reported.

Abstract
A single-stage current-fed DC-DC converter structure and control strategy is described which allows simultaneous control of both output voltage and current flowing in the input inductor. This solution is well suited for high-power-density applications, since it results in very reduced converter size and power loss. Moreover, a very fast control-to-output response is obtained, together with stable operation even for large load and reference variations. Static and dynamic converter performance is investigated, and design criteria are given. Experimental results obtained on a prototype are reported.
