    • The present invention relates to a commercial frequency alternating current discharge magnetic stimulator, comprising a input signal unit which enables 220 input voltage to be reduced to 9 voltage to be full-wave rectified to a diode bridge circuit; a zero cross switch (ZCS), wherein the signal from the input signal unit is input in a base of a first transistor of a differentiator, which amplifies the output of the differentiator, therefore, outputs 5 voltage of square wave whose pulse width is 500 μs at a zero point of the base of the first transistor; a magnetic output unit which enables 220 input voltage to be full-wave rectified to the diode bridge circuit and transmits pulse to a magnetic coil by being triggered to SCR.
    • 本发明涉及一种商用频率交流放电磁刺激器,其包括输入信号单元,其使得能够将输入电压降低到9个电压,以将其全波整流到二极管桥式电路; 零交叉开关(ZCS),其中来自输入信号单元的信号被输入到微分器的第一晶体管的基极中,其放大微分器的输出,因此输出5个脉冲宽度为500的方波电压 μs在第一晶体管的基极的零点处; 磁输出单元,其能够使220个输入电压被全波整流到二极管电桥电路,并通过触发到SCR将脉冲发送到电磁线圈。
