| dc.description.abstract | © 2019 IEEE. This paper presents the design of a two-stage 50W portable charger architecture with universal ac input and 5V/25W, 9V/45W, 12V/50W output. A 98.5% efficient valley-switched boost converter operating at 0.5-2MHz enables a 47% reduction in the buffer capacitor volume while a stacked-bridge LLC converter with a Variable-Inverter-Rectifier-Transformer (VIRT) offers greater than 96% efficiency across the wide output voltage range. The design demonstrates the potential and trade-offs of a two-stage architecture at this operating power. | en_US |
