Multi‐Layer MTDC Protection: Design and Simulation Assessment

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This study proposes a novel multi‐layer protection architecture for multi‐terminal DC systems that separates fault current‐limiting and interruption functions. By combining a thyristor‐based fault current limiter with an active resonance circuit breaker, the scheme significantly reduces peak fault currents and di/dt stress, enabling a more compact ...

A Modified Isolated Z‐Source AC–AC Converter With Inherent Commutation and Reduced Polarity Changer Switches

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
In this paper, a modified isolated Z‐source AC–AC converter with inherent commutation and reduced polarity changer switches is proposed. This converter enables flexible output voltage adjustment, determined by two degrees of freedom—namely, the high‐frequency transformer turns ratio and the duty cycle.
