    • An electric switching device using a switching mode power is provided. The electric switching device includes a switching controller for turning on or off a switching element at a predetermined frequency according to a switching signal, a transformer to which an input power is applied, for controlling the input power according to the on or off state of the switching element and for chopping the input power into a square wave frequency signal, a switch control output unit for rectifying the square wave signal and outputting a DC power, and a switch unit, which turns on or off according to the DC power supplied from the switch control output unit. Accordingly, an output voltage of a switching controller is maintained at a predetermined level even though the load, the output voltage and/or current or the operating current varies according to switching, thereby an on and/or off operation of the switch is stably performed.
    • 提供了使用开关模式电力的电开关装置。 电开关装置包括开关控制器,用于根据开关信号以预定频率接通或断开开关元件,施加输入电力的变压器,用于根据开关信号的接通或断开状态来控制输入功率 开关元件并将输入功率切断成方波频率信号;开关控制输出单元,用于整流方波信号并输出​​直流电;以及开关单元,其根据从所述开关元件提供的直流电力接通或断开 开关控制输出单元。 因此,即使负载,输出电压和/或电流或工作电流根据切换而变化,开关控制器的输出电压也保持在预定水平,从而稳定地进行开关的接通和/或断开动作 。
