Design and comparison of quadratic boost and double cascade boost converters with boost converter
2017 14th International Multi-Conference on Systems, Signals & Devices (SSD), 2017Basically, 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 ...

High efficiency quadratic boost converter
2012 Twenty-Seventh Annual IEEE Applied Power Electronics Conference and Exposition (APEC), 2012This paper presents a new soft-switched pulse-width modulated (PWM) quadratic boost converter which is suitable for applications with a wide fluctuating DC input voltage range, e.g. photovoltaic and fuel cells systems. The active switches are turned-on under zero-current and zero-voltage switching (ZC-ZVS) and turned-off with zero-voltage switching ...

An Improved Voltage-Mode Controller for the Quadratic Boost Converter
IEEE Transactions on Circuits and Systems II: Express Briefs, 2022An 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.

Quadratic Boost Converter for Green Energy Applications
2021DC–DC converters with high-voltage conversion ratio are widely used in renewable energy sources like PV, wind and fuel cells. Cascaded or quadratic DC–DC converters are the most practical solution to achieve a wide conversion ratio \(\left( {M = \frac{{V_{{\text{O}}} }}{{V_{{{\text{in}}}} }}} \right)\) and reduced current ripple.

AbstractIn this paper, a new transformerless buck–boost converter is proposed. This converter is based on combining two basic converters, including Cuk and traditional buck–boost converters, along with a voltage multiplier (VM) at the output side. The proposed semi‐quadratic buck–boost converter operates in continuous conduction mode (CCM) and provides

Switched Linear Control of Quadratic-Boost Converters
IEEE Journal of Emerging and Selected Topics in Power Electronics, 2019In this paper, a new observer-based switched linear control law is designed for output voltage regulation of quadratic-boost converters. The proposed controller is based on the min-type switching strategy. Switching behavior of the converter is considered in the design procedure. The system is based on the direct one-loop control scheme.

Noncascading quadratic boost converter for PV applications
2018 IEEE International Autumn Meeting on Power, Electronics and Computing (ROPEC), 2018In this paper a dc-dc switching quadratic step-up converter for photovoltaic applications is presented. The converter is based on a noncascading structure I-IIC. A model of the converter, steady-state characteristics and a controller design to regulate the input voltage (photovoltaic module voltage) are given.

Sliding mode controlled quadratic boost converter
2014 International Conference on Computation of Power, Energy, Information and Communication (ICCPEIC), 2014This paper deals with a quadratic boost converter which belongs to cascade boost family, controlled by sliding mode controller. In the cascade boost family, quadratic boost converter is the best trade-off when circuit complexity and modulator saturation is considered.
