Design and comparison of quadratic boost and double cascade boost converters with boost converter

2017 14th International Multi-Conference on Systems, Signals & Devices (SSD), 2017
Basically, the output voltage in renewable energy sources is improved using the boost converter, which is the key part in a photovoltaic chain. In this converter, the switching frequency is limited; hence the output voltage is reduced. To overcome this problem, two topologies are proposed; the quadratic boost converter results by combining the ...

An Improved Voltage-Mode Controller for the Quadratic Boost Converter

IEEE Transactions on Circuits and Systems II: Express Briefs, 2022
An improved voltage-mode controller (VMC) for the single-switch conventional quadratic boost converter (CQBC) is presented. It has a structure different from those of the existing voltage-mode controllers in that it avoids the possibility of dividing by zero and finding the square root of a term which could be negative.
