Abstract

This paper proposes a new resonant circuit enhanced with a new tracking control approach for a piezoelectric transformer-based LED lighting system. In this method, the LED driver architecture features full bridge phase shift converter with C-L-C series-resonant circuit along with the piezoelectric transformer. Then, the concept of tracking control is well designated into the FPGA controller such that a higher efficiency of operation can be better reached. Besides, since only the secondary current of resonant transformer is needed for the controller, it helps facilitate the circuit implementation. From experimental results, they solidify the feasibility of this method for modular LED lighting applications.
