Thermally Compensated Discontinuous Modulation Strategy for Cascaded H-Bridge Converters [PDF]
, 2018 A widely adopted multilevel converter topology is the cascaded H-bridge (CHB), as it can provide voltage and power scalability. However, since the CHB converter can be composed by cells with different remaining lifetime, it could be useful to delay a ...

IET Electric Power Applications, Volume 19, Issue 1, January/December 2025.In this paper, we proposed an open circuit fault diagnosis method based on mixed logical dynamical model. The experiment verified the effectiveness and feasibility of the fault diagnosis algorithm and reduced fault diagnosis time without increasing algorithm complexity. Abstract The T‐type three‐level rectifier has garnered significant attention due to

Performance Analysis of Various Three‐Phase Hybrid Transformerless Inverter Configurations
IET Power Electronics, Volume 18, Issue 1, January/December 2025.This study investigates hybrid transformerless inverter topologies for grid‐connected solar PV systems, focusing on minimising leakage current (LC) and maintaining common‐mode voltage (CMV) stability. A modified discontinuous pulse width modulation technique is proposed to reduce switching losses and enhance reactive power handling.

IET Power Electronics, Volume 17, Issue 14, Page 1973-1985, 4 November 2024.Using a high‐gain band‐pass filter, oscillations in the synchronous frame current measurements under unbalanced grid voltages are utilised to suppress current THD, and provide current limiting during severe faults. Active power ripple suppression is realised through dynamic gains on current measurements for each phase according to the relative voltage ...
