Analysis and Design of a Single-Switch High Step-Up Coupled-Inductor Boost Converter

IEEE transactions on power electronics, 2020
Analysis and design of a single-switch high step-up coupled-inductor boost converter are presented in this paper. With the aid of the coupled inductor, the proposed converter can achieve high-voltage gain without extreme duty cycle.

Coupled inductor based boost DC/DC converter

2016 7th Power Electronics and Drive Systems Technologies Conference (PEDSTC), 2016
The boost dc-dc converters are used to increase the magnitude of dc voltage. The renewable energy sources such as photovoltaic and fuel cell generate low magnitudes of voltage. To solve this problem, it is necessary to use a boost dc/dc converter. In this paper, a new boost dc-dc converter by using coupled inductor is proposed.

Single-Stage Boost Inverter With Coupled Inductor

IEEE Transactions on Power Electronics, 2012
Renewable power systems as distributed generation units often experience big changes in the inverter input voltage due to fluctuations of energy resources. Often, a front-end boost converter is added to step up the dc voltage when the energy resources are at a weak point.

Microfabricated coupled inductors for integrated power converters

Journal of Magnetism and Magnetic Materials, 2005
Abstract A microfabricated coupled inductor for low-voltage, high-current power converters is presented. The aim is to miniaturize such converters and improve their transient response using high-performance microfabricated inductors. These inductors have high power density enabled by a high-flux-density magnetic material (NiFe) and have the potential

Coupled Inductor based Non-Isolated Boost Converter

2020 International Conference on Smart Grids and Energy Systems (SGES), 2020
Smart grids use several distributed renewable energy sources. Renewable energy sources like photovoltaic modules provide a low output voltage which requires significant boosting before utilisation. Usual boost converter topologies can deliver the required gain but only when operating at extreme duty ratios.

PWM Inverters Using Split-Wound Coupled Inductors

IEEE Transactions on Industry Applications, 2008
The number of voltage levels available in PWM voltage source inverters can be increased by using an inverter leg with a split-wound coupled inductor and interleaved PWM switching of the upper and lower switches. The magnetizing inductance of the split-wound inductor filters the PWM-cycle instantaneous voltage differences between the upper and lower ...

Seven level asymmetric inverters with coupled inductors

2015 IEEE 13th Brazilian Power Electronics Conference and 1st Southern Power Electronics Conference (COBEP/SPEC), 2015
This paper proposes two seven level asymmetric inverter with coupled inductors that enable a reduction in the number of controlled switching devices. However, the lack of redundant states and difference in the maximum pole voltages reduce the performance of the inverters due to higher winding currents and saturation of magnetic core.
