Abstract
As a viable alternative to magnetic transformers in the power supply for portable electronics, this paper presents a miniaturized off-line travel adapter or charger for cellular phones using the piezoelectric transformer. Various design considerations in the design of ac PT adapters are investigated before coming up with the proposed pseudo-resonant topology. A prototype hardware design is also presented and verified by simulations and experiments
