摘要
A discharge lamp ballast apparatus includes a DC/DC converter having a transformer T1 and a DC/DC converter having a transformer T2, which are connected in parallel; a control section 4 for controlling the output voltages of the DC/DC converters by varying their duties with shifting the operation phases of the transformers T1 and T2 of the DC/DC converters; and a voltage-multiplier rectifier circuit having diodes 7-9 and capacitors 10-12 for generating a high voltage used for starting a discharge lamp 22 by utilizing the potential difference between the output voltages of the transformers T1 and T2. 展开▼
