A LED driving power supply based on buck-boost cascade quadtype buck topology
A novel LED driver is proposed and analyzed in this paper. The main circuit topology is based on a quadratic buck and a buck-boost. They share a switch through cascading, simplifying the topology and control strategy, reducing the cost of the control ...

A New Topology of Embedded Z-H Buck-Boost Converter [PDF]
In this paper, a new embedded Z-H (EZ-H) buck-boost converter is proposed. In this topology, two identical dc voltage sources are embedded in a LC network in a series connection with the inductors. The proposed converter eliminates the shoot-through (ST)

Comparison of Three Buck Topologies for Wide Output Voltage Applications
This paper investigates the suitability of three step-down dc-dc converter topologies as the final conversion stage in a wide output voltage modular ac-dc power supply. Single-phase, two-phase and three-level buck converters are evaluated over a wide range of outputs using analytical models and physical measurements.

EMC Analysis of the Inverting Boost/Buck Converter Topology
This paper describes the electromagnetic compatibility (EMC) analysis of an inverting buck/boost converter. The inverting buck/boost converter differs from other DC/DC converters, such as the noninverting boost or buck converters, in that one inductor terminal is connected to the ground and not to the input or output of the converter, i.e., neither ...

A New Circuit Design of Two-Switch Buck-Boost Converter
A conventional two-switch buck-boost (TSBB) converter can operate in buck, boost, and buck-boost modes. This paper introduces a new topology for a two-switch buck-boost converter with the same operation modes.

A Quadratic Buck-Boost Converter With Continuous Input and Output Currents
This study proposes a novel DC-DC converter topology that features a quadratic buck-boost voltage gain ratio. The quadratic gain of the converter enables it to achieve superior step-down or step-up capability when the duty cycle is higher or lower than ...

Presented a transformer‐less buck‐boost DC–DC structure with vast voltage range
Here, a transformer‐less buck‐boost topology is presented which can provide an appropriate voltage conversion ratio in both boost and buck mode. The voltage range of the proposed topology can be increased and decreased for the low content of the duty ...

Review of Voltage-Bucking/Boosting Techniques, Topologies, and Applications
As non-isolated step-up and step-down DC–DC converters are at present widely used in various fields, this review will summarize and introduce non-isolated step-up and step-down DC–DC converters in various aspects. First of all, the origin and development of power electronics technology and the generation and principle of certain basic non-isolated step-
