Radio Science, Volume 61, Issue 4, April 2026.Abstract A novel switch‐based Active‐Neutral‐Clamped (ANPC) inverter for low DC‐link voltage is presented in this paper. The proposed ANPC topology minimizes switches and achieves 1.5 times better voltage gain than standard inverters. The main objective of this design is to reduce active switches in the inverter to increase system efficiency.

IET Power Electronics, Volume 19, Issue 1, January/December 2026.High‐gain DC‐DC converters play a vital role in photovoltaic conversion systems. Achieving high gain often requires operating at extremely high duty cycles, which can lead to increased costs, higher power losses, and reduced system performance. To address these challenges, this study proposes a non‐isolated semi‐quadratic DC‐DC converter, which is ...
