IET Power Electronics, Volume 19, Issue 1, January/December 2026.This article presents a Fifteen‐level inverter topology that has a lesser number of switches (12) and can accommodate isolated DC sources. The total harmonic elimination (THD) of the proposed topology using genetic algorithm is within the IEEE 519 standards. Further, the fifteen‐level inverter is implemented in Hardware and firing pulses were generated

A transient and non-unit-based protection technique for DC grids based on the rate-of-change (R-o-C) of the fault induced travelling wave components [PDF]
, 2019 This paper presents a transient and non-unit-based protection scheme for consideration in DC grids of the future. The technique utilises the rate-of-change (R-o-C) of the associated travelling wave components following the occurrence of a fault to ...

IET Power Electronics, Volume 19, Issue 1, January/December 2026.This paper proposes a non‐contact method for measuring the turn‐off time of insulated‐gate bipolar transistor (IGBT) devices in modular multilevel converters (MMC) submodules, using the decay of load‐side common‐mode current. The technique leverages existing current‐sensing infrastructure and avoids intrusive modifications, enabling real‐time ...

Impedance-compensated grid synchronisation for extending the stability range of weak grids with voltage source converters [PDF]
, 2016 This paper demonstrates how the range of stable power transfer in weak grids with voltage source converters (VSCs) can be extended by modifying the grid synchronisation mechanism of a conventional synchronous reference frame phase locked loop (PLL).

A Coordinating Control for Hybrid HVdc Systems in Weak Grid
IEEE transactions on industrial electronics (1982. Print), 2019 A coordinating control strategy is proposed for a hybrid high voltage dc (HVdc) system comprising a capacitor commutated converter connected in series with a two-stage voltage source converter called “Vernier.” This approach ensures that 1) the tap ...

Blitzeinschlagsanalyse für rückwärtige Überschläge einer Hybridleitung [PDF]
, 2015 A new method to transfer energy over short and long distances is to use hybrid lines. In this paper a lightning surge analysis for backflashovers on overhead transmission lines with one DC and three AC systems on the same tower is considered ...
