Digitally Implemented Charge Control for LLC Resonant Converters
IEEE Transactions on Industrial Electronics, 2017 This paper proposes a digitally implemented charge control for LLC resonant converters. By analyzing the small-signal characteristics of the resonant capacitor, it is revealed that the resonant capacitor has exactly the same functionality as a resettable integrator in the charge control for a PWM converter.

Angewandte Chemie International Edition, EarlyView.Nitrogen K‐edge XAS and RIXS reveal signatures of structural and electronic relaxation in the photo‐induced spin‐crossover cascade of iron‐(II)‐tris(bipyridine). Oscillations of the 1s→π∗$1{\rm s} \rightarrow \pi ^*$ transition energy are correlated with the transient elongation of the Fe─N bonds.
