Mathematical model of the LLC resonant converter

Proceedings of Tomsk State University of Control Systems and Radioelectronics, 2020
The numerical-analytical model of the voltage regulator based on full-bridge LLC resonant converter is proposed in this paper. In the text of the article LLC converters operation algorithm on each working interval is investigated. The proposed mathematical model describes key elements behavior on duty cycle and allows the study of nonlinear dynamic ...

Short-circuit protection of LLC resonant converter using voltages across resonant tank elements

The Journal of Engineering, 2015
This paper describes two methods for the short-circuit protection of the LLC resonant converter. One of them uses the voltage across the capacitor and the other uses the voltage across the inductor of the resonant tank.

Ligand Engineering for Precise Control of Ultrathin CsPbI3 Nanoplatelet Superlattices for Efficient Light‐Emitting Diodes

Advanced Materials, EarlyView.
In this work, we introduce ancillary‐ligand‐mediated growth control of ultrathin CsPbI3 PeNPLs to achieve highly uniform thickness and reduced agglomeration. Strong ancillary‐ligand coordination to the perovskite surface regulates nucleation and improves surface passivation, enabling color‐pure emission and preferentially oriented superlattices.
