parallel resonance

n
(Electronics) the resonance that results when circuit elements are connected with their inductance and capacitance in parallel, so that the impedance of the combination rises to a maximum at the resonant frequency. Compare series resonance

There is the added issue of meeting international harmonic control requirements such as IEEE-519 which limits "the maximum frequency voltage harmonic to 3% of the fundamental and the voltage total harmonic distortion (THD) to 5% for systems with a major parallel resonance at one of the injected frequencies." Some form of filtering is subsequently recommended.
The series resonance ([f.sub.s]) appears at 1620 and 1647 MHz, while the parallel resonance ([f.sub.p]) is apparent at 1611 and at 1629 MHz.
Based on the equivalent circuit model, a parallel resonance can also be produced by Cp and Ls, where the capacitor can be seen to be open-circuited.
A stopband DMS with its parallel resonance equivalent circuit is reported in [17].
Besides, EPC only represents the first parallel resonance between inductor and the parasitic capacitance.
Hence, we present four topologies that are composite right/left-handed transmission line (CRLH TL) [21], dual-CRLH TL (D-CRLH TL) [22], series resonance and parallel resonance topology.
Consequently, transmission line [L.sub.1] and [L.sub.2] compensate the parasitic elements of PIN by resultant parallel resonance at on-state and series resonance at off-state in both of the structure.
When building the power delivery impedance profile from a combination of capacitors, an important feature is the parallel resonance, which develops between two real capacitors connected in parallel.
C3 provides an AC ground to assure the parallel resonance will not be affected by other parasitic like bond-wires, test board microstrip line effects and supply noises.
The properly tuned PC is in parallel resonance with the grid-to-ground network capacity at fundamental power supply frequency.
For lossless unit cell equivalent circuit model, L-C parameters of series and parallel branches are extracted from the series and parallel resonance frequencies, respectively.
