In this thesis, a contactless inductive charging module is studied and implemented. The front stage is a boost converter with power-factor correction (PFC) function. The second stage is a full-bridge phase shift converter with the contactless transformer. The final stage is a buck converter with charging function. The characteristics of the iron core with different air gap are discussed and the operating principles are presented. Finally, a prototype circuit is implemented in the laboratory. A contactless inductive charging module with AC input (110 V) is performed. The air gap of the contactless transformer is adopted for 7 mm. A 12 V/4.5 Ah lead-acid battery using CC-CV charging algorithm is realized by single chip PIC16F877. Experimental results show that the efficiency of the contactless transformer is 73 %, the total efficiency can reach 63 %, and the power factor is 0.98.
