• High-Performance Megahertz-Frequency Resonant DC–DC Converter for Automotive LED Driver Applications

  IEEE Transactions on Power Electronics · 2020 · 47 citations

  This paper introduces a megahertz-frequency resonant dc-dc converter that inherently achieves a load-independent output current while maintaining high efficiency across a wide output voltage range. These properties make the proposed converter well-suited for automotive light-emitting diode (LED) driver applications, where a varying number of LEDs need to be driven with a constant current. The proposed converter achieves load-independent output current by utilizing an LCL-T resonant network, and…

• Reduction of AC Winding Losses Due to Fringing-Field Effects in High-Frequency Inductors With Orthogonal Air Gaps

  IEEE Transactions on Power Electronics · 2020 · 46 citations

  Senior authorCorresponding

  In high-frequency inductors, ac winding losses are affected by skin and proximity effects, including uneven current distribution due to fringing magnetic fields around air gaps. It is well known that fringing effects can be mitigated using distributed air gaps. This article is focused on an orthogonal air-gap approach, which is a distributed air-gap technique where gaps are placed in core segments parallel with the windings and in core segments perpendicular to the windings. The orthogonal air-g…

• A Two-Stage Automotive LED Driver With Multiple Outputs

  IEEE Transactions on Power Electronics · 2021 · 40 citations

  Senior authorCorresponding

  This article presents a two-stage automotive LED driver architecture delivering independently regulated output currents to multiple LED strings. The system consists of a multiphase noninverting buck-boost front-end stage, which allows for a wide battery voltage range, followed by high-frequency immittance-network-based LCL-T resonant converters, which operate as current sources over wide output voltage ranges. The two-stage buck-boost + resonant (BB+resonant) architecture takes advantage of the…

• Steady-State Indeterminacy in Lossless Switched-Mode Power Converters

  IEEE Transactions on Power Electronics · 2022 · 19 citations

  Senior authorCorresponding

  In this article, it is shown for the first time that lossless switched-mode power converters may not possess a unique steady-state solution. Rather, they can exhibit an inherent <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">indeterminacy</i> in their steady-state behavior, and a unique solution is only found when losses are included in the analysis. Even more interestingly, it is shown that lossless converters of <italic xmlns:mml="http://www.w…

• Balancing Multiphase FCML Converters With Coupled Inductors: Modeling, Analysis, Limitations

  IEEE Transactions on Power Electronics · 2024-04-25 · 16 citations

  articleOpen access

  This paper investigates the modeling, analysis, and design methods for passively balancing flying capacitor multilevel (FCML) converters using coupled inductors. Coupled inductors synergize with FCML converters by reducing inductor current ripple, reducing switch stress, and, as proven in this paper, by providing flying capacitor voltage balancing. This enables FCML topologies to be scaled well to larger systems. This paper proves that coupled inductors can solve the unbalancing problem in many…
