Description
Introduction Most electronic ballasts and switching power supplies use a bridge rectifier and a filter capacitor to derive raw dc voltage from the utility ac line.
This simple rectifying circuit draws power from the line when the instantaneous ac voltage exceeds the capacitor’s voltage.
