Constant current and ripple control of LED driver without electrolytic capacitor
Dianzi Jishu Yingyong, 2018 When the traditional unloaded boost-buck LED driver power supply has a high power factor, it will produce significant low-frequency ripple current. Based on the buck-boost topology, this paper presents an innovative LED drive power technology.

Cost‐Benefit Analysis of the European Union Carbon Border Adjustment Mechanism in Fertilizer Trade
Agribusiness, EarlyView.ABSTRACT The carbon border adjustment mechanism (CBAM), launching 2026, will charge EU importers for embedded carbon emissions, aiming to reduce emissions but raising import costs. Shifts in demand following implementation may reduce carbon emissions, but importers will bear the cost of increased prices.
