A Family of Transformerless Quadratic Boost High Gain DC-DC Converters
Energies, 2021 This paper presents three new and improved non-isolated topologies of quadratic boost converters (QBC). Reduced voltage stress across switching devices and high voltage gain with single switch operation are the main advantages of the proposed topologies.
