WebGeomagnetic Induced Current (GIC) is the result of coronal mass ejections (CMEs) from the sun. CMEs interact with the earth’s magnetosphere through a process called electromagnetic induction. This results in geomagnetic disturbances (GMD). There are two kinds of solar activity that have the potential to disrupt our lives on earth: solar ... WebDynamic balance is important in power systems employing high fre- quency, requiring high efficiency or utilizing large pulse currents. The paper is an extension of earlier work which dealt primarily with the effects of threshold voltage and transconductance (gain) mismatch on current and switching energy unbalance1, 2, 3.
