Consisting of one voltage-fed full-bridge on the high voltage side and one current-fed full-bridge with an inductor and active clamp circuit on the low voltage side as well as a high-frequency transformer shown  above This setup has no circulating current but high voltage stress on the switches but can operate in ZVS or ZCS and requires moderate complexity control circuit. This configuration also shows a lot of potential and can be improved by reducing the voltage stress on the switches.
