Conventional H-bridge and recent multilevel inverter topologies

, 2021
Traditional H-bridge inverters are composed of four switches controlled with any SPWM strategy, such as bipolar, unipolar, or hybrid. Among these methods, the bipolar SPWM reduces the leakage current by providing constant CMV.

Ferroionic‐Assisted, Charge‐Driven Polymorphic Phase Engineering for Multilevel Memristive Devices

Advanced Materials, EarlyView.
A CuInP2S6/Mo0.92W0.08Te2 heterostructure enables a gradual semiconductor‐to‐semimetal phase transition through Cu+ ion migration and charge accumulation. The spatially engineered 2H/1T′ mixed phases produce continuously tunable conductance states in a two‐terminal geometry, while suppressing depolarizing fields and stabilizing the metastable 1T′ phase.
