A Quadratic Boost Converter Suitable for Fuel Cell-Powered Electric Vehicles

This study presents a non-inverting transformer-less Boost converter with a higher voltage conversion ratio, resulting in quadratic growth of the output voltage with modest increments in the duty cycle rate. The continuous input current of this converter simplifies the input filter design and enhances fuel cells' lifetime and stability. Additionally, compared to existing architectures, this converter reduces the voltage and current stresses on semiconductor components, making it a promising alternative to other quadratic Boost converters. As a result, this topology appears to be a viable alternative for the remaining quadratic Boost converters. The inclusion of common-ground switches, which eliminate the need for additional components for gate driver isolation, is one of the main features that make this topology distinct. As a result, the converter fabrication cost and size are reduced. The proposed converter's steady-state analysis is thoroughly explained. Stresses placed on semiconductor devices. Then, a meaningful comparison between the proposed circuit and its counterparts is provided to understand this converter's unique attributes.
