IET Power Electronics, Volume 19, Issue 1, January/December 2026.This article presents a dual‐source novel nine‐level inverter (DSN2LI) featuring minimal devices. Utilizing eight switches, which include 2 bidirectional switching devices and 2 uneven dc links, the proposed DSN2LI generates nine levels. The DSN2LI employs the utilization of trinary geometric DC links.

Time indicator of the Human Development Index [PDF]
, 2017 The Human Development Index, computed by the United Nations, has been challenged since it does not measure the real development of a country. It needs to be combined with other indexes and ratios (poverty, Gini index).

IET Power Electronics, Volume 19, Issue 1, January/December 2026.This paper proposes an improved offline pulse density modulation strategy for the SWISS rectifier to achieve low input current distortion and high power factor at high switching frequencies. Experimental results at 38.4 kHz reduce THDi from over 30% to ≈10%, while high‐frequency simulations at 172.8 kHz achieve THDi of 3.3% and PF = 0.9954.
