CONSTITUTION:When a power source 101 is energized, positive pulsating voltage is applied to the collectors of transistors 301, 302. Since the output of a full- wave rectifier 102 is pulsating, a low voltage is generated across a capacitor 502 through a capacitor 501 and a resistor 504. Thus, a base current is flowed through resistors 304, 305, an inverter is thus oscillated, the transistors 301, 302 are alternately conducted, and a high frequency voltage is inducted at the secondary coil 2c of an oscillation transformer 306. This high frequency voltage is applied to a load 4 for a discharge lamp or the like.,下面是Power source专利的具体信息内容。
