Circuit arrangement for operating at least a light source with improved crest factor |
摘要 |
<p>The circuit has a rectifier [D7-10] coupled to the mains input and has a positive and negative outputs. The circuit has a power factor correction function that is provided by a combination of a charging pump and a valley-fill circuit. The charging pump provides a voltage [UN2] delayed by an inductance [L2] for the valley fill circuit.</p> |
