In this paper, a methodology to develop SPICE-based models of complex magnetic devices
is presented. The proposed methodology is based on a reluctance equivalent circuit, which …

This paper presents a design, simulation, and evaluation procedure of a variable inductor
(VI) for a recently proposed dc-grid LED driver. The design procedure is based on the use of …

A conventional pulse frequency modulation (PFM) controlled LLC resonant converter
requires a wide switching frequency operating range to regulate the output voltage. There …

This paper presents a novel variable inductor (VI) based LED driver for DC grid lighting
applications. The proposed driver requires only a series inductor and a transformer as major …

Magnetic devices are used in the majority of power electronic applications, eg power
electronic converters, mains filters or burst/surge protection. Typically, they are the bulkiest …

This article presents a concept of controller actuation mechanism for self-oscillating resonant
converters (SORCs). Simplicity, robustness, and cost-effectiveness are among the main …
