Open‐circuit fault diagnosis method for three‐level neutral point clamped inverter based on instantaneous frequency of phase current

open access: yesEnergy Conversion and Economics, 2020
Because the three‐level neutral point clamped (NPC) inverter has the advantages of a large output capacity and high output voltage, it is widely used in wind energy and solar energy power generation.

Calpain small subunit homodimerization is robust and calcium‐independent

open access: yesFEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Three-level GaN inverter with SiC diodes for a possible three-phase high power solution

open access: yesThe Journal of Engineering, 2019
GaN device is a potential alternative to SiC as a wide band gap device. At present, there are almost no high-voltage GaN devices above 650 V, which makes an inverter design difficult for three-phase input using the standard two-level (2L) inverters ...

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

open access: yesFEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.
