Abstract
Official abstract text for this publication.
An LLC resonant transformer ( 19 ) for a lamp ( 5 ) comprises a primary circuit ( 19 ) and a secondary side ( 30 ) galvanically isolated therefrom. During operation of the LLC resonant transformer ( 19 ), a first switch ( 21 ) and a second switch ( 22 ) of a half-bridge to which an LLC resonant circuit ( 25 - 27 ) of the primary circuit ( 19 ) is connected are actuated in a clocked fashion. A load ( 5 ) to which an output ( 35 ) on the secondary side ( 30 ) supplies energy is detected on the basis of a measured variable (iavg) acquired in the primary circuit ( 20 ). The half-bridge ( 21, 22 ) is variably controlled on the basis of the measured variable (iavg) that is acquired in the primary circuit ( 20 ) and indicates the load ( 5 ).
First claim
Opening claim text (preview).
What is claimed is: 1. A method for operating an LLC resonant converter ( 19 ; 79 ) for a light-emitting means ( 3 ; 5 ; 50 ), wherein the LLC resonant converter ( 19 ; 79 ) has a primary-side circuit ( 20 ; 80 ), which comprises a half-bridge ( 21 , 22 ) and an LLC resonant circuit ( 25 - 27 ), and a secondary side ( 13 ; 30 ) galvanically isolated therefrom, the method comprising: controlling the half-bridge ( 21 , 22 ) by clocked switching of switches ( 21 , 22 ) of th…
