In this work, we present the optimization of two disk-type piezoelectric transformers (PTs) by using the elite Genetic Algorithm (GA) and the finite-element solver, NTUPZE. The design goal is to optimize the voltage gain as well as the efficiency for the applications of the backlighting modules of liquid crystal display (LCD) panels. The optimization process is parallelized by the MPI library and a PC cluster for improving the computation efficiency. The simulated results were also verified with measured data.
