Predictive Controller for Fourth Order Buck Topologies

INTELEC 05 - Twenty-Seventh International Telecommunications Conference, 2005
In this paper, an approach for the design of predictive controller for fourth order buck topologies is proposed. The controller is designed to achieve the load voltage regulation against load and source disturbances. A zero ripple technique is used to reduce the ripple in inductor current.

30.6 A 98.6%-Peak-Efficiency 1.47A/mm2-Current-Density Buck-Boost Converter with Always Reduced Conduction Loss

IEEE International Solid-State Circuits Conference, 2023
Buck-Boost converters are commonly used in the Li-ion battery-powered mobile devices to convert a varying battery voltage (e.g., 2.7V to 4.2V) to a mid-3V output voltage $(\mathrm{V}_{\text{OUT}})$ for supplying various function blocks such as RF power ...

Power factor preregulators based on combined buck-flyback topologies

IEEE Transactions on Power Electronics, 2000
The limitation imposed on the achievable power level by the IEC 1000-3-2 standard in buck-derived power factor preregulators, is overcome by using a combined buck-flyback power stage. Two different step-down converters are proposed in this paper, which incorporate an auxiliary flyback stage.

Dynamic String Interconnection with Buck Converter Topology

2010
Inhomogeneous illumination, e.g. due to partial shading of one photovoltaic module in a photovoltaic string, limits the common current of all modules of the string. Depending on the string configuration, partial shading reduces the output voltage of the string dramatically by bypassing the affected module.

A 90.4% Peak Efficiency 48-to-1-V GaN/Si Hybrid Converter With Three-Level Hybrid Dickson Topology and Gradient Descent Run-Time Optimizer

IEEE Journal of Solid-State Circuits, 2023
This work presents a direct 48–1-V DC–DC point-of-load (POL) converter for efficient high-voltage conversion. Conventional hybrid topologies face limitations of large number of off-chip components and limited operation ranges.

Fault-Tolerant Design of Three-phase Dual-Buck VSI Topologies

IECON 2019 - 45th Annual Conference of the IEEE Industrial Electronics Society, 2019
This paper presents fault tolerant topologies for the three-phase dual-buck voltage-source inverter (VSI). Using the proposed topologies, increased reliability is obtained, which is fundamental in many safety-critical applications. The solutions intend to achieve fast changing between main and redundant branches through the combination of several power
