Abstract
An AC-DC converter includes a main switch that is controlled according to an input AC line voltage. The main switch is allowed to be switched when a level of the input AC line voltage is within a regulation band, and is prevented from being switched when the level of the input AC line voltage is not within the regulation band. The regulation band can be dynamically adjusted based on load condition. The AC-DC converter can be a buck, boost, or buck-boost converter.
