The proposed converter generates high voltage gain in comparison with the conventional dc-dc converters. Duo to using active-clamped circuit in the proposed topology the voltage stress on main switch is reduced. In addition the zero voltage switching (ZVS) in ON-state of main switch is obtained. In this paper the performance of the proposed structure is investigated in continues current mode (CCM) and discontinues current mode (DCM). Moreover, the voltage gain in CCM and DCM operations are calculated. To prove the correctness operation and also the given equations, the simulation results in PSCAD/EMTDC software are used.
