This thesis proposes a NiCd battery charging circuit based on contactless inductive charging techniques. Without direct metal connections, inductive techniques adopt the magnetic coupling mechanism for contactless inductive charging to promote the safety of charging systems. The ER core is used to transfer power and the phase-locked loop control is used to track the resonant frequency of the various resonant tanks in charging processes. Besides, the transform efficiency is improved by the compensative capacitors. The charging circuit using CC charging algorithm is realized by bq2002 fast-charge management ICs. Finally, the contactless charging system is implemented to verify the performance on a 12V/1800mAh NiCd battery. Experimental results and charging processes are provided for verification. The best coupling efficiency is 80% in charging processes.
