Abstract
A voltage sampling system is provided. The voltage sampling system includes a voltage sampling device, two optic-fiber transmission lines and a control device. The voltage sampling device includes a voltage-dividing resistor module, a common mode rejection circuit and an analog-to-digital converter. The voltage-dividing resistor module generates a first and a second divided voltages according to a voltage source. The common mode rejection circuit receives the first and the second divided voltages to perform a common-mode noise rejecting process to generate an output voltage. The analog-to-digital converter converts the output voltage to generate a digital data signal. The two optic-fiber transmission lines transmit the digital data signal and a clock signal respectively. The control device receives the digital data signal from the analog-to-digital converter and the clock signal to perform a digital data processing.
