    Abstract:

    Capacitance voltage dividers are often utilized to monitor voltage values in high power electrical pulse devices. The amplitude linearity of the capacitive voltage divider characterizes the consistency of the voltage value monitored. In this paper, the principle of the ceramic capacitance divider is analyzed, and the performance of the ceramic capacitance divider is simulated by the simulation software under the rectangular pulse high-voltage source(500 V-4 kV) with a pulse width of 200 ns and the impulse high-voltage source(10 kV-100 kV) with a half-width of 10 μs respectively, and the design and processing are carried out. The results show that the amplitude linearity of the ceramic capacitor voltage divider is 1.5% within the range of 500 V-100 kV, and the linearity is good. The voltage divider calibrated under small signals can be applied to the measurement of large signals.
