    • The present invention relates to a switch control circuit, a switch control method, and a converter using the same.An input voltage rectified from an AC input in a converter is transmitted to an inductor, and output power is generated from an inductor current by the input voltage. The converter includes a power switch connected to the inductor to control the inductor current and a sense resistor having a first end connected to a ground and a second end connected to the AC input. At a time point that a sense voltage generated in the sense voltage reaches the peak point and then decreased to an on-reference voltage, the power switch is turned on. The on-reference voltage is a sense voltage at a resonance start time point between a parasite capacitor of the power switch and the inductor.
    • 本发明涉及开关控制电路,开关控制方法和使用该开关控制方法的转换器。 从转换器中的AC输入整流的输入电压被传输到电感器,并且通过输入电压从电感器电流产生输出功率。 转换器包括连接到电感器以控制电感器电流的电源开关和具有连接到地的第一端的检测电阻器和连接到AC输入端的第二端。 在感测电压中产生的感测电压达到峰值点然后降低到基准电压的时间点,电源开关被接通。 参考电压是功率开关的寄生电容器和电感器之间的谐振起始时间点处的感测电压。

    • An apparatus for preventing withdrawing and insertion of a carriage of a circuit breaker is disclosed. When a circuit breaker main body is inserted, an interlocking unit operates by interworking with the carriage withdrawing and inserting preventing apparatus, and while the circuit breaker is being closed, a withdrawal and insertion handle prevents a lead screw from being rotated by the interlocking unit. Thus, when the circuit breaker performs a closing operation, unnecessary withdrawing and inserting operation of the carriage is basically prevented to thus prevent various safety accidents, a contact resistance, a temperature increase, and damage to a device resulting from a breakdown.
    • 公开了一种用于防止断路器滑架的拆卸和插入的装置。 当插入断路器主体时,互锁单元通过与滑架退出和插入防止装置相互作用而操作,并且当断路器被关闭时,撤回和插入手柄防止引导螺钉被联锁单元旋转。 因此,当断路器执行闭合操作时,基本上防止了滑架的不必要的抽出和插入操作,从而防止了由于击穿而引起的各种安全事故,接触电阻,温度升高和对设备的损坏。
