TL;DR: A comprehensive review and comparison of CM schemes for different types of dc-link applications with emphasis on the application objectives, implementation methods, and monitoring accuracy when being used is provided.

TL;DR: In this article, a multichannel constant current LED driver with dynamic high-frequency sinusoidal voltage regulation is proposed, which is composed of one resonant inverter and several LCL-T resonant rectifiers.

TL;DR: An online monitoring scheme is proposed for buck converters, aiming to estimate the ESR and capacitor parameters of AEC at the output side using large-signal load transient trajectories and has a relatively low sampling frequency.

TL;DR: A hybrid dynamic compensation (HDC) scheme, which incorporates a combination of zero-perturbation dynamic Compensation (ZPDC) and ripple compensation, which can suppress the fast-scale instabilities and also ensure average inductor current tracks a desired sinusoidal reference which is not possible with the ZPDC scheme alone.

TL;DR: In this paper, an online ESR estimation method of aluminum electrolytic capacitor (AEC) was proposed by using the wavelet transform (WT) based time-frequency analysis, and the relationship between ESR and the jump amount of output voltage at turn- off moments was analyzed first, and then the ESR calculation model was derived using WT with the Wavelet basis of the first derivative of Gaussian function.
