Abstract
Disclosed herein is a charger for electric vehicles, which has a wide output voltage range. The charger is a slow charger having an improved configuration to respond to a wide output voltage range as well as output change. The charger may achieve limited switching loss and reduced noise via soft-switching operation, thereby enabling high-efficiency large-power Power Factor Correction (PFC) and increasing conversion efficiency of a DC/DC converter.
