series resonance

[′sir·ēz ′rez·ən·əns]
(electricity)
Resonance in a series resonant circuit, wherein the inductive and capacitive reactances are equal at the frequency of the applied voltage; the reactances then cancel each other, reducing the impedance of the circuit to a minimum, purely resistive value.

It is necessary to point out that the characteristic can be made less compliant when a smaller series capacitor leg (closer to the series resonance) is used.
When we have zero immittances, the series resonance frequency [[omega].sub.se] and parallel resonance frequency [[omega].sub.sh] are obtained.
Then, the number of lumped elements of impedances or admittances at midpoint can be reduced when [Y.sub.ses] and [Y.sub.shs] are only parallel resonance and [Z.sub.ses] and [Z.sub.shs] are only series resonance such as CRLH TL topology.
The series resonance between the source and the filter can be reduced if the strategy is K>>([Z.sub.S]+[Z.sub.F]).
1 and is based on a wellknown series resonance circuit with a full bridge excitation system, a solution often used in energy transfer systems [1], [8], [15], [16].
For frequencies slightly lower than [f.sub.0], the parallel one is inductive while the series one is capacitive and they compose a new series resonance [f.sub.0l].
Due to the series resonance, high electric potential and strong electric field occur where the total voltage on serial inductors is not equal to that on serial capacitors in the transmission line, as can be seen in the aperture electric field distribution.
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.
It is apparent that when paired together the series resonance of neither individual capacitor--which would manifest as a low[S.sub.11]--is observed (5.1 and 3.2 GHz for the 3.3 and 6.8 pF capacitars, respectively, as listed in the table).
There is known one such uncontrolled AC/DC converter with parallel and series resonance alternation (PSA) having a constant-power operation zone in its output characteristics [5].
However, for drastic variation impedance, the load is in series resonance or parallel resonance within a very narrow band, etc., the AAV may not accurately represent the overall impedance level within the frequency range we care.
For an approximately 1.0 nF capacitor, toward the lower end of the frequency spectrum, the series resonance is at issue.
