Abstract

The invention belongs to the field of an acquisition circuit, and particularly relates to an acquisition module applied to a high-voltage power supply. The acquisition module applied to the high-voltage power supply comprises a signal transmitting unit, a voltage signal acquisition unit and a current signal acquisition unit. The signal transmission unit is used for connecting with the output end of a flyback transformer and transmits a voltage signal and a current signal which are output from the flyback transformer to the voltage signal acquisition unit and the current signal acquisition unit. The voltage signal acquisition unit is connected with the signal transmitting unit and is used for acquiring the voltage signal which is transmitted by the signal transmission unit. The current signal acquisition unit is connected with the signal transmitting unit and is used for acquiring the current signal which is transmit by the signal transmission unit. According to the acquisition module applied to the high-voltage power supply, when the output end of the flyback transformer outputs a high level, a resistor R1 and a resistor R2 acquire the output high level, a capacitor C1 and a capacitor C2 which are connected in parallel can effectively conduct a circuit when a high-frequency signal is transmitted, thereby realizing a simple circuit structure.
