Active PFC

- Jun 14, 2019-

Instead of coupling the charging condenser directly to the rectifier a boost convertor is interconnected. The boost convertor triggers an always constant direct voltage on the link capacitor out of the restified sinus signal.


EN61000-3-2 states that it is not allowed to use a LED driver with a power consumption > 25W without active PFC.


Ottima′s LED drivers have active PFC on all relevant parts.
