Capacitive divider with a circular array of capacitors to reduce self

Capacitive voltage dividers are key tools to measure high-voltage pulses. A drawback of these dividers is the self-resonance caused by the inductance of the connections, resulting in unwanted oscillations in the measured signal.

Power Divider Basics

Reactive Power Dividers leverage capacitors and inductors to divide power. Since they don''t dissipate much power, they''re a high-frequency option; however, reactive power dividers operate over a narrow frequency band. Resistive Power Dividers use resistors to divide power. Since they dissipate much of the input power as heat, they''re not the most efficient.

6 FAQs about [The frequency divider needs several capacitors]

Why is a capacitive divider frequency dependent?

Frequency Dependence: The voltage division ratio of a capacitive divider is frequency-dependent due to the variation in capacitive reactance with frequency. This means that the output voltage will vary with the frequency of the input signal.

Why do capacitor dividers have a frequency-dependent response?

Capacitive dividers have a frequency-dependent response due to the capacitive reactance of the components. The reactance of a capacitor (X C) is inversely proportional to the frequency (f) and capacitance (C): X C = 1 / (2πfC) As the frequency increases, the reactance decreases, affecting the voltage division ratio.
