Low-Voltage Stress Buck-Boost Converter With a High-Voltage Conversion Gain [PDF]
IEEE Access, 2020 The conventional buck-boost converter has the advantages of simple structure, low cost, and the capability to achieve both voltage step-up and down. However, due to the negative impacts of the parasitic parameters of the device, the voltage conversion gain of the conventional buck-boost converter is greatly limited.

Ultra-High Step-Up Interleaved Converter With Low Voltage Stress [PDF]
IEEE Access, 2021 In this paper, a new type of interleaved high step-up converter including a coupled inductor is proposed. The proposed converter has an interleaved configuration on the input side to reduce the ripple of the input current and increase the power level. Moreover, a stacked structure on the output side provides a high input/output (I/O) voltage gain.

A T-Type Switched-Capacitor Multilevel Inverter With Low Voltage Stress and Self-Balancing
IEEE Transactions on Circuits and Systems I: Regular Papers, 2021 This paper proposes a novel T-type multilevel inverter (MLI) based on the switched-capacitor technique. The proposed inverter not only achieves that the maximum voltage stress of the switches is less than the input voltage but also has a voltage boost ...
