Analysis of losses in the core of an electrodeless fluorescent lamp

An investigation of magnetic core losses of an electrodeless fluorescent lamp is presented in this paper. These losses can be divided into two different kinds: static, which is related to hysteresis effects, and dynamical, associated to parasitic effects. Experimental results (at 25° C) demonstrate that the total losses, in nominal condition point, are approximately 3.18 W, what represent 3.18% of the power supplied to the lamp. In this same point, the static losses are approximately 1.31 W and the dynamic losses about 1.87 W. Based on this, the static losses represent about 41% of total loss related to the magnetic core while dynamical losses represents 59% of total loss.
