A Step up DC-DC Converter with Coupled Inductor for Renewable Energy Applications using MPPT

Parvathi Mohan, Sreeja E A

In this paper, an isolated high step up dc-dc converter is included. In the past few decades, power electronic converters are exploited for industrial demands and they play a major role in high power equipments for different applications. Use of power electronic converters is ever increasing in the processing of electrical energy in industrial applications such as uninterrupted power supplies, distributed photovoltaic generation systems, fuel cell energy conversion systems and other AC utility mains applications. Boost converters are widely used in the low to high dc-dc applications. In the recent years, significant efforts have been made on improving the performance of high power boost converters. In this project a isolated high step-up dc-dc converter with low voltage stress is presented. The proposed converter achieves extremely large voltage conversion ratio with appropriate duty cycle and reduction of voltage stress on the power devices. The topology utilizes coupled inductor. The leakage inductance energy can efficiently be discharged. Since the device stresses are low in this topology, low voltage MOSFETs with small RDS (on) values can be selected to reduce the conduction loss. The Perturb and Observe algorithm was implemented for tracking the maximum power from the PV panel. These features improve the converter efficiency. When compared to other topologies the proposed converter contain only one switch which simplify the circuit configuration and improve the system reliability. All these factors improve the circuit performance in the high step-up applications
