摘要： To provide a low-cost self-excited inverter driving circuit exhibiting an excellent operational efficiency. A main inverter section is so constructed that a part of output signals is fed back by a resonance loop circuit to cause a self-excited oscillation to occur in the vicinity of a resonance frequency decided by leakage inductors and capacitors on the secondary side of a high voltage transformer, thereby performing an inverter operation. It is further arranged that a halt interval setting signal, which is generated by a triangular wave forming circuit and a control section, is applied to the main inverter section, thereby halting the inverter operation in accordance with the halt interval setting signal.

摘要： The present invention provides a load failure protection circuit and a discharge lamp driving apparatus, which can exactly detect a failure even if the failure arises in any of a plurality of discharge lamps, and can stop drive of the discharge lamp. A part of currents of corresponding CCFLs (201 and 202) flows into two bypass resistors (21a and 21b), further, a full current of the bypass resistors (21a and 21b) flows into a resistor for full current detection (22), and its voltage drop is inputted into a control IC (1) as a feedback signal. On the other hand, cathodes of Zener diodes (25a and 25b) are connected to end parts of the bypass resistors (21a and 21b) on each CCFL side. When potential of any one of the cathodes rises by a load failure, a corresponding one of the Zener diodes (25a and 25b) generates a Zener voltage for a transistor (26) to become conductive. Therefore, since a feedback signal line connected to the collector of the transistor (26) is made at the ground potential forcibly, it is decided to be a load failure by the control IC (1), and drive of the discharge lamp is stopped.
摘要翻译：本发明提供了一种负载故障保护电路和放电灯驱动装置，其即使在多个放电灯中的任何一个中出现故障也能够精确地检测到故障，并且可以停止放电灯的驱动。相应的CCFL（201和202）的电流的一部分流入两个旁路电阻（21a和21b），此外，旁路电阻（21a和21b）的全电流流入用于全电流检测的电阻 22），其电压降作为反馈信号输入到控制IC（1）中。另一方面，齐纳二极管（25a和25b）的阴极连接到每个CCFL侧的旁路电阻器（21a和21b）的端部。当任何一个阴极的电位由于负载故障而上升时，相应的一个齐纳二极管（25a和25b）产生用于晶体管（26）变为导通的齐纳电压。因此，由于连接到晶体管（26）的集电极的反馈信号线被强制地接地，所以决定为控制IC（1）的负载故障，停止放电灯的驱动。
