Abstract:
Supercapacitors are advantageous in terms of high power density, wide operating temperature range, and long cycle life. To better utilize the high power density feature of supercapacitors and achieve fast charging, this study proposes a dual-mode charging method, and a dual-mode fast charger for supercapacitors that utilizes both continuous and fine-tuned pulse currents. By tuning the voltage across the output inductor, the proposed charger improves the pulse characteristics of the conventional forward converter in that the transitions between the continuous and pulse currents are much faster. Preliminary experimental results demonstrate the effectiveness of the proposed charger.
