摘要: Universal-line (90–264V ac ) AC-DC adapter poses a major challenge to maintain high efficiency across the entire line. At same time, reduction of its weight and size is required. Usually, low-power implemented with single-stage flyback converter. To further improve efficiency, valley switching technique secondary synchronous rectifier applied it. However, it still has low efficiency. Therefore, two-stage adapters are required have higher under this paper presents comparative evaluation for 60W as conventional adapter. In adapter, PFC stage consists boost converter or buck DC-DC LLC Experimental results obtained on 60W(16.5V/3.65A) notebook provided
