Description

technical field [0001] The invention is a device capable of effectively reducing the response time of the step response of a resistance voltage divider and improving the performance of the voltage divider, which is suitable for the measurement of high-voltage pulses and belongs to the technical field of high-voltage measurement. Background technique [0002] The error generated when the resistor divider measures the impulse voltage is related to the product of the resistance value and the stray capacitance to ground. Therefore, the error can be reduced by reducing the resistance value and reducing the stray capacitance to the ground. However, if the resistance value is too small, on the one hand, it will affect the shock wave generated by the generator; on the other hand, because it is difficult to damp the oscillation between the residual inductance and stray capacitance, the resulting step response will produce high overshoot. Therefore, reducing the measurement error mai...
