Fully Decoupled Current Control and Current Balancing of the Modular Structure for LED Color-Mixing System

Abstract: For LED color-mixing, the different color LEDs need to be controlled independently, so a fully decoupled current control and current balancing of the modular structure is proposed for LED ...
