| description | This article introduces a new fully soft switched ultra-high step-up quadratic converter. The proposed converter benefits from several advanced features including high voltage gain at low duty cycle, low switch voltage stress, low sum of diodes voltage stress, switching at ZVS condition for switches, low ripple continuous input current, and common ground between the input and load. These advantages are achieved by integrating the quadratic structure with an auxiliary circuit consisting of coupled inductors, switched capacitors, and active clamp techniques. Furthermore, the presented converter mitigates the reverse recovery problem of all diodes especially the input side diodes which is a challenge in many quadratic base converters. These properties have contributed to providing an efficient converter with wide applicability. The converter is fully analyzed, its superiority to other structures is shown, and a 200 W laboratory prototype validates the theoretical analysis. |
