Independent Control of Multicolor-Multistring LED Lighting Systems With Fully Switched-Capacitor-Controlled $LCC$ Resonant Network

Current imbalance is a major problem in multistring LED lighting systems. Significant research efforts have been directed to solve the problem by either an active or passive approach. However, in view of some system requirements or other emerging lighting applications, independent control of different LED strings is getting more important to obtain different desirable brightness and/or color spect...
