With the capacitor in parallel, there is now an additional source of energy, which can take up some/all of the burden of supplying current to the inductive load (when it resists changes in current till it sets up its field), after which the source takes over again and recharges the capacitor.
When multiplied by the voltage across the load this leads to the same increased level of power, given by Eq. (22.6), as with parallel compensation. As shown by Eq. (22.6), compensating capacitors on the secondary side of an IPT circuit allow for an increase in power transfer by the Q of the secondary circuit.
This solution is not feasible, since the amount of the grid impedance, thus its resonance frequency, varies depending on the operating conditions of the power system. The application of parallel compensation instead of series compensation is possible as well. But the parallel capacitors may cause super-synchronous resonances .
It is observed that as the size of the compensation capacitor is increased, the low-frequency pole location ω1 decreases in frequency, and the high-frequency pole ω2 increases in frequency. The poles appear to “split” in frequency.
Objective of compensation is to achieve stable operation when negative feedback is applied around the op amp. Miller - Use of a capacitor feeding back around a high-gain, inverting stage. Miller capacitor only Miller capacitor with an unity-gain buffer to block the forward path through the compensation capacitor. Can eliminate the RHP zero.
if you put parallel both L and N will surpresed against high amperage reactance power from the load. capacitor in AC parallel for PFC working like dampening the load. yes it's charging and giving output in the next cycle so your reactance power decreasing.
