HIGH GAIN SWITCHED LC CONVERTER WITH LOWER OUTPUT VOLTAGE RIPPLE FOR PHOTOVOLTAIC APPLICATIONS

  • Unique Paper ID: 186214
  • PageNo: 1325-1330
  • Abstract:
  • High step-up voltage conversion is essential in renewable energy systems to efficiently interface low-voltage sources with high-voltage loads.This project introduces a non- isolated high step-up DC-DC converter that integrates active switched-inductor (ASL) and switched capacitor cell (SCC) techniques. The proposed converter achieves a high voltage gain by strategically configuring capacitors and diodes to interconnect the input and load sides. A key advantage of this design is the division of input current, which reduces inductor size and enhances overall efficiency. Additional benefits include a high step-up ratio at a low duty cycle,reduced voltage ripple and reduced voltage transients across switches.A comprehensive anal- ysis of the converter’s operating principles,design equations,and device stress is done.Finally, a laboratory prototype is developed and tested under various operating conditions in continuous conduction mode to validate the theoretical findings.The sim- ulation validates the theoretically claimed analysis.The efficacy of the suggested topology is confirmed by the simulation re- sults.MATLAB/SIMULINK is used to perform the simulation. In the rated state, the maximum efficiency is 93%
