Abstract

The invention provides a precise AC/DC broadband voltage dividing device and method. The device comprises a resistance voltage dividing module and a buffer module. The resistance voltage division module comprises a high-end resistor and a low-end resistor; the buffer power supply module comprises a buffer; the high-end resistor is configured to receive an input voltage and perform voltage divisionthrough the resistor, and a signal after voltage division is output to the front end of the buffer from the low-end resistor; the high-end resistor and the low-end resistor are connected in parallelwith a compensation capacitor to correct the frequency response curve of the voltage divider; and the buffer converts the high-internal-resistance signal into a low-resistance output signal to carry out broadband precision measurement.

Description

technical field [0001] The disclosure belongs to the technical field of voltage division, and in particular relates to a device and method for precision AC / DC broadband voltage division. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] There are two methods commonly used in voltage division, the resistance method and the capacitance method. The working principle of the voltage divider is introduced as a resistor divider, as follows figure 1 is the schematic diagram of the voltage divider of the resistor, and the calculation formula is shown in formula (1): [0004] [0005] In the formula: U1——input high voltage, V; [0006] U2——output low voltage, V; [0007] R1, R2 - voltage divider resistance, Ω. [0008] Resistance method, when using constantan wire with small temperature coefficient or Kama wire with small temperature coeffici...
