چکیده
|
In this paper, a new structure of step-up dc-dc converter by using coupled inductor and active-clamped circuit is proposed. the proposed converter generates high voltage gain in comparison with the conventional dc-dc converters. due 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 continuous current mode (ccm) and discontinuous current mode (dcm). moreover, the voltage gains 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.
