A Developed Structure of Step-Up DC/DC Converter by Using Coupled Inductor and Active Clamped Circuit
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. 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 m...
متن کاملHigh Step-Up Interleaved DC/DC Converter Using VM Cell for PV Applications
This work proposes a high step-up interleaved dc/dc topology utilizing a VM (voltage multiplier) cell suitable for PV applications. The VM cells D/C (Diode/Cap.) are cascaded among the phases to approach a high voltage gain. Besides, the voltage converting ratio of the presented structure can be improved by extending the VM cells and it also leads to drop in the normalized voltage stress throug...

متن کاملA State Space Modeling of Non-Isolated Bidirectional DC-DC Converter with Active Switch
In this paper, analysis, design and implementation of non-isolated soft-switching bidirectional DCDC converter with an active switch are described. The proposed topology gives the output voltage as twice as the input voltage and enhances the efficiency up to 94.5% and 92.9% for boost and buck mode operation by proper selection of the duty cycle. Soft switching can be achieved at both steps up a...
