摘要： There is provided a voltage controlled oscillator (VCO) stably generating a clock of a 50% duty from a simple circuit to have an excellent duty correction function in noise. The VCO includes a VCO unit and a duty correction unit. The VCO unit generates first and second signals having a 180° phase difference to each other with an oscillation frequency according to a control voltage to output the first and second signals through first and second oscillation output terminals. The duty correction unit generates a clock signal of a 50% duty according to the first and second signals through the first and second oscillation terminals.

摘要： A backlight inverter for an LCD panel which is capable of detecting a fault in a transformer device or an open-lamp condition and performing a control operation to stop its operation upon detecting the fault in the transformer device or the open-lamp condition. The inverter supplies a PWM signal through a switch in normal operation. The inverter also detects a voltage corresponding to current flowing through each lamp in a lamp device and determines from the detected voltage whether the open-lamp condition has occurred. The inverter further detects a voltage at a midpoint of secondary windings of the transformer device and determines from the detected voltage whether the fault exists in the transformer device. In the event of the open-lamp condition or the fault in the transformer device, the inverter turns off the switch.
摘要翻译：一种用于LCD面板的背光逆变器，其能够检测变压器装置中的故障或开灯状态，并且在检测到变压器装置中的故障或开灯状态时执行控制操作以停止其操作。逆变器在正常工作状态下通过开关提供PWM信号。逆变器还检测与灯装置中流过每个灯的电流相对应的电压，并根据检测到的电压确定是否发生了开灯状态。逆变器进一步检测变压器装置次级绕组中点处的电压，并根据检测到的电压确定变压器装置中是否存在故障。在开灯状态或变压器设备故障的情况下，变频器关闭开关。
