A comparison between the open-chain (OC) and daisy-chain (DC) transformer structures for current-balancing multiple LED strings will be presented. The methodology starts with deriving a general analytical expression for describing the current distribution in both structures. The derived model is then used to study the differences in the string currents to the variations of the LED string voltages,...
Increases in system loads and in levels of penetration of renewable energy, together with limited investment in transmission infrastructure, are fostering the need for a smarter and more dynamically controllable grid. FACTs devices can be used to dynamically control the grid and more efficiently route power and thus mitigate these stresses, but such devices are either too complicated and expensive...
