| Popis: | 102 The 1.2kW Li-ion battery charger with wide output voltage range is implemented in this paper. It is mainly consisted of power factor corrector and battery charging stage. There are four kinds of power factor corrector structure, including the conventional Boost Converter, the interleaved, bridgeless and the semi-bridgeless. Also, there are two kinds of battery charging stage, including the conventional full-bridge converter and full-bridge converter with current-doubler rectifier. The proposed charger is compared by the experiment to choose the better structure and promote its characteristic. Power factor feature is controlled by UCC28070 to achieve the high power factor correction. Then, battery charging stage is controlled by digital signal processor of dsPIC30F4011 to achieve the wide output voltage and the CC/CV charging function. Finally, a 1.2kW Li-ion battery charger with wide output voltage range is designed and implemented to verify the feasibility. The experimental results show that the proposed system can achieve the high power factor correction, universal input voltage, wide charging voltage range and the highest efficiency of 94.3%. |
