Abstract: The inventive power supply converts the low-frequency alternating current source into high-voltage direct current. An induction windings network series connected to the fluorescent tube provides a feedback signal to a pair of bridging transistors which then respectively alternates to be on or off to output a high-frequency, high-voltage signal for the tube to use. The network is connected so that the inductors provide the feedback signal, the signal having a resonant frequency suitable for activating the tube. The light emitted in accordance with this invention is continuous, due to the inventive feedback, in comparison to the light emitted by a fluorescent tube utilizing a transformer and a starter.
