Parameters of synchronous generator Inductive reactance
's and resistances, in p.u., at rated power and voltage [S.sub.N] and [U.sub.N] 1.
Assuming the loop-tuning mechanism balances the inductive reactance
of the loop itself with the capacitive reactance of the tuning capacitor, then the feedpoint impedance of the loop is the radiation resistance plus the loss resistance.
This novel miniaturization technology uses a below-resonant monopole which possesses a capacitive reactance and a below-resonant loop which has an inductive reactance
. The capacitive reactance of the monopole can be cancelled at the reduced resonant frequency by loading an inductive loop.
Also the measured results show that the cross-polarization level (LHCP) is lower than the co-polarization level (RHCP) by more than 20 dB at the broadside direction, which is due to the fact that the probe-fed horizontal rectangular strip can provide the necessary capacitive reactance to compensate the inductive reactance
caused by the vertical probes.
But as the test frequency is increased, the inductive reactance
of the LISNs increases, and the voltage drops in the LISNs.
The bipolar transistor with an inductive reactance
between the base and the ground can also generate a negative resistance (See Figure 5).
It can be recalled that the tapered microstrip edges introduce inductive reactance
, which can be used to effectively tune out the capacitive reactance offered by the feed strip.
This can be accomplished by having very high capacitance or very low inductive reactance
. Because most gaskets are conductive, minimizing inductive reactance
is the goal.
The implementation of the inductive reactance
, direct-coupled filter in coplanar waveguide is shown in Figure 18.
The choice between a capacitive and inductive reactance
at this intermediate design stage is determined primarily by the impedance of the original required load impedance and the desire to use a length of series transmission line that is as short as possible.
