摘要： The high voltage supply for a picture tube comprises a high voltage transformer, which generates the anode voltage of the picture tube, and a high voltage module with a switched mode power supply for providing a grid voltage, which is higher than the anode voltage. The output of the high voltage transformer is coupled to the transformer of the switched mode power supply, for adding the output voltage of the switched mode power supply to the high voltage of the high voltage transformer. Preferably, the transformer of the switched mode power supply provides the high voltage isolation, and at least the high voltage part of the module including the transformer is potted with a resin. The high voltage module provides advantageously also an output for a connection to the anode of the picture tube, so that the module can be used with present high voltage transformers, without requiring any modification. The primary side of the switched mode power supply comprises a control stage with adjustable means for setting a specific output voltage of the power supply. In a preferred embodiment, this output voltage is adjustable between 300 and 500 Volts, with respect to the high voltage of the high voltage transformer.

摘要： A speed-up circuit 10 is connected to a detection line 6 for feeding back the high voltage detection value of a high voltage detection circuit 5 to a high voltage stabilizing circuit 1. When a power supply switch is turned on, since a PNP transistor 12 of the speed-up circuit 10 is turned on, a resistor 11 is connected to the detection line 6, so that the high voltage detection value is reduced forcedly. Accordingly, the high voltage stabilizing circuit 1 increases the peak value of a flyback pulse generated by a resonance-type power supply circuit 2 to output higher high voltage thereby to shorten the rising time of the high voltage output supplied to the anode of a CRT. After the lapse of the predetermined time from the turning-on of the power supply switch, since the terminal voltage of a capacitor 13 having been charged through a resistor 14 exceeds almost the voltage at a point A, the PNP transistor 12 is turned off, so that the resistor 11 is separeted from the detection line. Accordingly, the responsibility of the flyback pulse is prevented from being degraded at the time of the abrupt change of the load of the CRT.
摘要翻译：加速电路10连接到检测线6，用于将高电压检测电路5的高电压检测值反馈给高电压稳定电路1.当电源开关导通时，由于PNP晶体管12 加速电路10接通，电阻器11与检测线6连接，使得高电压检测值被强制地减小。因此，高电压稳定电路1增加由谐振型电源电路2产生的回扫脉冲的峰值，以输出较高的高电压，从而缩短供给CRT的阳极的高电压输出的上升时间。在从供电开关接通经过预定时间之后，由于已经通过电阻器14充电的电容器13的端子电压几乎超过了点A处的电压，所以PNP晶体管12截止，使得电阻器11从检测线分离。因此，在CRT的负载的突然变化时防止回扫脉冲的作用降低。

摘要： In a video display operable at multiple horizontal scanning frequencies, a synchronized high voltage generator is substantially undisturbed during synchronizing source selection or interruption. The generator comprises a controlled oscillator generating a drive signal. A source of pulses synchronizes the controlled oscillator and has a plurality of scanning frequencies. A high voltage generator is coupled to the drive signal and generates a display energizing supply. The scanning frequencies occur in two frequency bands, and when synchronized the oscillator generates the drive signal having a frequency only in a higher frequency band of the two frequency bands. In a further inventive arrangement a high voltage generator for a video display is operable at a plurality of horizontal scanning frequencies and is controlled such that the high voltage supply remains substantially constant during an interruption of horizontal scanning pulses from the source.

摘要： An anode voltage (high voltage) of a CRT is detected by a voltage division. When it is detected by a comparator that the reduction of the high voltage has exceeded the controlled range of a high voltage stabilizing loop, two switches will be on. When one switch is on, the controlling end of a processing circuit controlling the luminance will be low in the potential and the direct current level or amplitude of a video signal will be limited. Thereby, the luminance will be controlled and the high voltage will become high. Meanwhile, when the other switch is on, the ABL operating voltage will forcibly become low and, even after the two switches become off, the average level of the luminance will be controlled. Thereby, the high voltage will return within a short time into the controlled range of the high voltage stabilizing loop and will be stabilized.
