Litz Wire Pulsed Power Air Core Coupled Inductor
IEEE Transactions on Industry Applications, 2014A methodology for designing high-current air core pulsed power coupled inductors is presented with emphasis on simplicity. Standard inductor design is based on derated current densities and magnetic flux densities to make the most efficient utilization of materials, but the presented pulsed power inductors have low duty cycle and are designed based on ...

Inductor loss calculation of coupled inductors for high power density boost converter
2014 International Power Electronics Conference (IPEC-Hiroshima 2014 - ECCE ASIA), 2014The interleaved boost converter with coupled inductors which achieves high power density has gained great attention in automotive applications. However, the temperature of the inductor tends to be high because loss density is increased by the high power density.

Coupled inductor characterization and SPICE modeling
Fifth Annual Proceedings on Applied Power Electronics Conference and Exposition, 1990A complete coupled inductor characterization method, including leakage flux, is described, and its SPICE model is presented. Another SPICE model is developed for p-p ripple current determination in the windings of the coupled inductor in a switching converter and its use is extended to AC stability and audiosusceptibility analyses. >

Coupled inductor based boost DC/DC converter
2016 7th Power Electronics and Drive Systems Technologies Conference (PEDSTC), 2016The 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, 2012Renewable 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, 2005Abstract 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

High Step-Up Converter With Coupled-Inductor
IEEE Transactions on Power Electronics, 2005In this study, a high step-up converter with a coupled-inductor is investigated. In the proposed strategy, a coupled inductor with a lower-voltage-rated switch is used for raising the voltage gain (whether the switch is turned on or turned off). Moreover, a passive regenerative snubber is utilized for absorbing the energy of stray inductance so that ...

PWM Inverters Using Split-Wound Coupled Inductors
IEEE Transactions on Industry Applications, 2008The 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 ...
