Abstract
An AC-DC power converter includes a rectifying circuit for rectifying the AC signal. The AC signal is supplied to a switching mode power supply for regulation and final filtering to obtain the output DC signal. A baseline generator in series between the rectifying circuit and the switching mode power supply ensures that there is always a minimum voltage level present in the signal that is applied to the switching node power supply.
