Optimal Modulation Strategy for Current-Source Converter to Reduce DC-Link Current Ripple
IEEE transactions on industrial electronics (1982. Print), 2023As one of the most important performance indices of a current-source converter, dc-link current ripple is closely related to the modulation strategy. Excessive dc-link current ripple not only reduces the system efficiency but also increases the total ...

Strategies to therapeutically modulate cytokine action
Nature Reviews Drug Discovery, 2023Cytokines are secreted or membrane-presented molecules that mediate broad cellular functions, including development, differentiation, growth and survival. Accordingly, the regulation of cytokine activity is extraordinarily important both physiologically and pathologically.
