Abstract
For renewable energy systems, power electronics are significant because they reduce fuel costs, increase efficiency, and increase reliability. Recently, some converter topologies are achieving up to 400V for grid application from solar PV modules using two-stage boost converters. So, a quadratic boost converter is designed with a double frequency approach to achieve an output voltage of more than 400V. The proposed converter’s steady-state analysis in CCM and DCM is examined with 93%efficiency to figure out how to express overall gain in terms of duty ratios and MOSFET operational switching frequencies.
