    • Disclosed are a switch controller, a switch control method, and a converter based thereon. The switch controller generates an input sensing voltage corresponding to the input voltage of the converter, and compares the input sensing voltage with a predetermined first reference value. The switch controller generates a zero cross detection signal with a first level or a second level depending upon the comparison result, and generates a reference clock signal varying in frequency in accordance with one cycle of the zero cross detection signal. The switch controller generates digital signals by using the reference clock signal and the zero cross detection signal. The digital signals synchronize with the zero cross detection signal, and increase in accordance with the reference clock signal during a half of one cycle of the zero cross detection signal, while decreasing in accordance with the reference clock signal during the other half cycle of the zero cross detection signal. The switch controller generates a reference signal with a voltage level corresponding to the digital signal.
    • 公开了一种开关控制器,开关控制方法和基于其的转换器。 开关控制器产生与转换器的输入电压相对应的输入感测电压,并将输入感测电压与预定的第一参考值进行比较。 开关控制器根据比较结果产生具有第一电平或第二电平的零交叉检测信号,并且根据过零检测信号的一个周期产生频率变化的参考时钟信号。 开关控制器通过使用参考时钟信号和过零检测信号来产生数字信号。 数字信号与零交叉检测信号同步,并且在零交叉检测信号的一个周期的一半期间根据参考时钟信号增加,而在零的另一半周期期间根据参考时钟信号减小 交叉检测信号。 开关控制器产生具有与数字信号对应的电压电平的参考信号。

    • A flexible ionizer uses soft X-ray and has a head unit generating soft X-ray whose wavelength is 1.2˜1.5 Å, a soft X-ray protect unit shielding the leak of the soft X-ray from the head unit, and a power control unit supplying a control signal and control voltage to the head unit. The head unit is positioned outside of the soft X-ray protect unit with the flexible ionizer further having a flexible tube protecting a high voltage cable that connects the head unit and power control unit from external impact or vibration and letting the user bend the head of the head unit at an arbitrary angle toward a charged body if necessary, a connecting device letting the ions generated at the window positioned inside of the body of the ionizer emit toward the charged body by connecting one end of the flexible tube and the head unit, and a connecting device connecting the other end of the flexible tube and the body of the ionizer. The high voltage power lines in the flexible tube are molded to prevent short circuits occurring at a near distance between the high voltage power lines and mutual induction voltages occurring. The short circuit and the mutual induction voltage are caused by the mutual influence of the high voltage lines.
