Beschreibung
Zusammenfassung:	A drive circuit of a light source is suitable for driving a hot cathode tube and has a preheating function. The drive circuit adopts a primary side inductor of a transformer to replace the resonant inductor in the prior art so as to simplify the circuit structure of the drive circuit and reduce the complexity and the design cost thereof. The drive circuit has the characteristics of reducing temperature and compensating impendence so that the stability of the system circuit is optimal.
