Single-Phase Virtual-Ground Transformerless Buck–Boost Inverters
IEEE Transactions on Power Electronics, 2023 This article presents a new family of transformerless buck–boost voltage-source inverter topologies for photovoltaic systems. Due to variations in irradiance, temperature, and shading effects, the terminal voltages of photovoltaic panels can vary, making the use of buck–boost inverters crucial. The proposed topologies have a virtual-ground feature that

A novel dual-leg DC-DC converter for wide range DC-AC conversion
Automatika, 2022 This paper proposes DC–AC Dual-leg dual-stage Conversion (DDC) and DC–AC Direct single-stage conversions (DSC). Conventional energy conversion system has only two-stage conversion, so it has some drawbacks such as huge power loss, less conversion range ...

Circuit for clamping bridge overvoltages in voltage-fed quasi-Z-source converter [PDF]
, 2016 Unlike the voltage source converter, the Z-source converter can boost as well as buck the input voltage. However, the presence of physically large components in the impedance network introduces large parasitic inductances into power device commutation ...

Resonant CLL Non-Inverting Buck-Boost Converter [PDF]
Journal of Power Electronics, 2013 This paper presents a resonant non-inverting buck-boost converter in which all switches operate under ZCS conditions. In a symmetric configuration, a CLL resonant tank along with an inverter arm and a rectifying diode are employed. The diode is turned off at ZCS and hence the problem of its reverse recovery is obviated also.
