Reliability and Efficiency Evaluation of Cascaded Two-stage Boost Converters
This study investigates the impact of variations in the intermediate DC bus voltage on the efficiency and reliability of cascaded two-stage boost converters. The assessment of reliability follows the AS/NZS IEC 61709:2019 standard and references MIL-HDBK-217F. The findings indicate that there is not always a direct correlation between conversion efficiency and converter reliability. The optimal condition for both reliable and efficient operation is when the electrical stresses are evenly distributed between the two boost converters.
