Why is a capacitor self-resonant?
As more systems run at ever higher frequencies and switching speeds, capacitor design and selection have become even more important. The capacitor self-resonant frequency causes your capacitor to stop behaving like a real capacitor and start behaving more like an inductor at high frequency.
What is a decoupling capacitor selection algorithm?
A decoupling capacitors (decaps) selection algorithm based on maximum anti-resonance points of the power distribution network and the quality factor (Q) of the capacitor is proposed. The experiment...
What happens when resonance equals capacitive reactance?
Resonance occurs when the inductive reactance equals the capacitive reactance. This can lead to an increase in current or voltage at the resonant frequency, which can cause damage to the equipment or system. In an electric power system, a harmonic is a voltage or current at a multiple of the fundamental frequency of the system.
What is a capacitor self-resonant frequency?
A capacitor self-resonant frequency can range from low MHz values to GHz values. In measurements, you can easily determine the impedance spectrum of your particular capacitor using frequency sweeps and measuring the output with an oscilloscope. You can also easily do this with a vector network analyzer.
How can a detuned reactor avoid resonance?
This resonance can be avoided by putting a detuned reactor in series with the capacitor. The reactor shall be such that the tuning frequency with the capacitor shall be less than the dominant harmonics. This combination of power factor correction capacitor and detuned reactors behaves inductively to frequencies above the tuning frequency.
Why is a capacitor a problem at low frequencies?
This important effect is unnoticeable at low frequencies, but it becomes a major problem related to signal integrity, power integrity, and impedance matching at high frequencies. The ideal model for a capacitor can be derived from Maxwell’s equations by defining a model with two infinitely large perfect conducting plates.
