A DC inductor comprising a core structure () comprising one or more magnetic gaps (), a coil () wound on the core structure (), at least one permanent magnet () positioned in the core structure, the magnetization of the permanent magnet () opposing the magnetization producible by the ...
In this case a 3.3µH inductor was selected, which solved the sub-harmonic instability over the full input voltage and load range, see figure 28. This effect can also be simulated with the Richtek Designer simulation tool. For another example where wrong inductor value selection can lead ...
This paper introduces an optimized DC–DC converter that employs a modified switched inductor-capacitor technique to achieve ultra-high voltage gain for renewable energy systems. The development is based on adding one cell of modified switched inductor (

DC-DC电路中电感的意义及选择
A DC-DC converter includes an inductor, a switch module, and a pull-up circuit or a pull-down circuit. The inductor has a first node and a second node, and the second node is couple
converter. For the inductor, the rated current should not be less than that of the output of the DC-DC converter. At the rated current, the DC resistance of the inductor should be such that the voltage drop across the inductor is less than 2 percent of the rated voltage of the DC-DC...
(PFC) circuit. A PFC ensures that the current drawn from the grid is sinusoidal. The PFC may consist of an inductor, but this is usually too bulky. Especially for higher power levels a switch mode converter, typically a step up converter(boost converter) is used. However, this requires a...
This study presents the analysis, design, and implementation of a DC/DC boost resonant-inductor converter with the stable operation when using a sliding-mode control. In addition, the control scheme provides zero-current switching, fast transient response, and soft converter start-up. Thus, the ...
