The target of this research is a design of constant and high efficiency driving system for a low pressure UV lamp. An UV lamp system is one of wide range electrical equipments for semiconductor manufacturing and sterilization, etc... It is essential the technique of constant output for high added value device. A design target of driving system for low pressure UV lamp of conversion efficiency is 90[%], UV lamp of output stability within ${\pm}7.5[%]$, and lamp power is over 200[W]. The results meet the target of this study well, and have a benefit of domestic market occupation and enable to export. And if protection circuits were developed, it increases the stability of a electronic ballast for UV lamps.
