Improvement on low voltage power supply of Na(Hg) lamp
Shen Li · Journal of Hangzhou Teachers College · 2000
The low voltage power supply of Na (Hg) lamp used in experiment usually uses inductance to operate as current limiter. In consequence of design and technology's insufficient, it gives off larger noise and heat. On the other hand, stored energy in inductance will make a high voltage to damage the lamp when power is turned off. In this paper we use capacity to operate as current limiter and work out a way to solve completely those problem of inductance 's power supply.
