Risk of resonance due to power-system harmonics
The installation of capacitors in a power system (in which the impedances are predominantly inductive) can, however, result in total or partial resonance occurring at one of the harmonic frequencies. Because of harmonics, the current I C circulating through the PFC capacitors is higher compared to the situation where only the fundamental current I 1 is present.

Effect of various capacitors on frequency response: 1. Effect of coupling capacitors: The reactance of the capacitor is X c = 1/2∏f c. At medium and high frequencies, the factor f makes X c very small, so that all coupling capacitors behave as short circuits. At low frequencies, X c increases. This increase in X c drops the signal voltage across the capacitor and reduces the

6 FAQs about [The effect of resonance on capacitors]
What causes resonance in a circuit involving capacitors and inductors?
Resonance of a circuit involving capacitors and inductors occurs because the collapsing magnetic field of the inductor generates an electric current in its windings that charges the capacitor, and then the discharging capacitor provides an electric current that builds the magnetic field in the inductor. This process is repeated continually.
What is a resonant capacitor?
Resonant capacitors are able to store and discharge energy to achieve specific circuit behaviors that can improve power conversion efficiency, reduce losses, and minimize switching stress. For advice on designing circuit elements for high-frequency filters and noise suppression, contact us.
How does frequency affect the reactance of a capacitor?
The capacitor’s reactance is inversely proportional to the frequency, and reactance decreases with increased frequency. When the inductor and capacitor are connected in the series, the total impedance of the circuit with frequency is as per below the graph.
How does capacitance affect resonance frequency?
・When the capacitance and the ESL are smaller, the resonance frequency is higher, and the impedance in the high-frequency region is lower. ・The larger the capacitance, the lower is the impedance in the capacitive region. ・The smaller the ESR, the lower is the impedance at the resonance frequency.
How does Resonance Affect A capacitor bank?
Thus, capacitor banks themselves may be affected by reso- nance, and may fail prematurely. This may even lead to plant or feeder shutdowns. Resonance is a condition where the capacitive reactance of a system offsets its inductive reactance, leaving the small resistive elements in the network as the only means of limiting resonant currents.
What is resonance effect?
Resonance can be defined as the sensitivity against a certain vibration frequency in mechanical structures. For an electronic circuit, the circuits with only one capacitor and coil are called the resonance circuits. As it is known, the resonance effect is one of the important negative effects in terms of current harmonic.
