Astragali Radix (AS) is a widely used herb in traditional Chinese medicine, with calycosin as its main isoflavonoid. Our previous study discovered that calycosin triggers host defense peptide (HDP) production in IPEC-J2 cells. The aim of this study i

Abstract For the dual three‐phase permanent magnet synchronous motor(dual‐PMSM), the deadtime can introduce fifth and seventh current harmonics, and they are only constrained by the small stator leakage impedance, which means even if there are on

Abstract Voltage‐controlled voltage‐source inverters (VVSIs) have been widely used in microgrids. Typically, LC filters are adopted by the VVSIs to improve the quality of the output voltage. Resonances of the LC filters that may cause oscillation

Due to their inherent topology characteristic, current source grid-connected photovoltaic inverters cannot realize low voltage ride through (LVRT) during a serious sag in the grid voltage. Based on mathematical models of three-phase current source gr

The droop controlled grid-connecting inverter (DC-GCI) has been widely used in microgrid (MG). However, the power flow of the droop control is very sensitive to the fluctuation of grid frequency and voltage magnitude, which will result in a very fast
