    摘要: A discharge lamp illumination circuit 1 has a DC-AC conversion circuit 3 for effecting AC conversion upon receipt of a DC input and detection circuits 12, 13 for detecting a voltage and a current of a discharge lamp 10. The circuit controls power output from the DC-AC conversion circuit 3, thereby controlling illumination of the discharge lamp 10. The DC-AC conversion circuit 3 has an AC transformer 7, switching elements 5H, 5L, and a resonance capacitor 8. The resonance capacitor 8 and an inductance component of the AC transformer 7 or an inductance element 9 are brought into series resonance. The detection circuits 12, 13 detect the voltage and current of the discharge lamp 10 through use of a detection winding 7v of the AC transformer 7 and the inductance element 9.

    摘要: Switching elements S1, S2 connected in series are provided on the secondary side of a pulse transformer T to which an input voltage is supplied from a DC power supply E. On the primary side of the pulse transformer T, switching element S3, S4 are provided, and a regenerating unit RG including a current limiting inductor L1 and a regenerating inductor L2 is connected to the DC power supply E and the primary side of the pulse transformer T. A current is limited by the inductor L1 during an on time of the element S3 or S4, whilst a current is regeneratively supplied to the DC power supply E by using the inductor L2 during the off time of the elements S3, S4.
