Lossless Snubber for GaN-Based Flyback Converter With Common Mode Noise Consideration

IEEE Access, 2022
The previous lossless snubber for flyback converters, although with a small number of components, simple control and high power conversion efficiency, has no consideration for electromagnetic interference (EMI).

Dynamic Retinal Pathology in Glaucoma Progression Revealed by High‐Resolution Functional Imaging In Vivo

Laser &Photonics Reviews, Volume 20, Issue 5, 6 March 2026.
In this work, we investigated the dynamic retinal pathology of glaucoma from onset to late stages through longitudinal in vivo high‐resolution imaging in a silicone oil‐induced ocular hypertension (SOHU) glaucoma mouse model. We developed an optimized adaptive optics two‐photon excitation fluorescence microscopy (AO‐TPEFM) technique for morphological ...

Research on Peak‐to‐Average Power Ratio Control Method for Switched Reluctance Pulse Generator

IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.
Addressing the different requirements for peak output power when SRPG supplies power to pulse loads and DC loads, the peak‐to‐average power ratio (PAPR) is taken as the generation performance optimisation parameter. By investigating the power characteristics of the SRPG, the influence of control parameters on the PAPR is studied.

A Flyback Converter With Novel Active Dissipative Snubber

IEEE Access, 2022
The active clamp flyback converters (ACF) can provide features of high power density and high power efficiency. However, ACF is usually applied to in the applications of medium-to-high power range. For a low power application, the ACF may not be a cost-efficient choice.
