Zusammenfassung:A current regulator for non-isolated, line voltage LED Driver circuits solves the problem of LED flicker caused by line noise in the visible frequency range. In one aspect of the invention, LED flicker frequency may be increased beyond the line frequency. In another aspect, line voltages in excess of LED voltage ratings may be tolerated. The driver may be implemented using discrete circuit elements or in software and utilizes separate current regulation for different segments of an AC line voltage cycle.
