Dynamic model of fluorescent lamp implemented in PSpice

This paper presents a discharge arc model which can represent approximately both static and dynamic characteristics of a typical fluorescent lamp controlled by a power electronic circuit. The proposed model was developed from the combination and modifications of the classical Cassie and Mayr equations. The equations have been expressed in a form suitable for incorporation into circuit simulators employing the nodal analysis method of equation solving. The model has been test implemented in the PSpice circuit simulator. Simulated and experimental results appear to be in good agreement.
