This paper proposes a Z-source converter based flyback converter with a new active clamp control method. With this control methodology, the energy in the leakage inductance can be fully recycled. The absorbed leakage energy transferred to the output and input side will achieve zero voltage switching for the main switch. Thus, switching loss can be reduced. A Z-source converter network is incorporated between the power source and converter main circuit to achieve high efficiency. Compared to the conventional methods, this technique can achieve high efficiency at any condition, where the efficiency is not affected by the leakage inductance
