Abstract
A high power factor regulator circuit which includes a variable multiplier, permitting the high power factor regulator circuit to be used with a number of input line voltage levels. In one embodiment a comparator determines the multiplication or gain factor to be applied in a control loop by comparing the rectified AC input voltage to a predetermined threshold value.
