So, to correct the power factor, an ideal parallel capacitor will simply make for a new total impedance of ∣∣∣ ZCZL ZC +ZL ∣∣∣ = |ZL|2 RL> |ZL| | Z C Z L Z C + Z L | = | Z L | 2> | | which means we'll draw less apparent power than before -- thus, satisfying the objectives of power factor correction! But, what about real capacitors?
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.
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.
By finding "the magnitude of the power supply voltage", "the magnitude of the current flowing in the RLC parallel circuit", and "the power factor of the RLC parallel circuit," the active power , reactive power , and apparent power can be calculated. The apparent power can be obtained by the following equation.
Adding a capacitor in parallel will increase equivalent capacitance of circuit, thus Xc (= 1/wC) should decrease, which is contrary of what we wanted to do. Remember, Z = R + jX Z = R + j X For an inductor XL = ωL X L = ω L and for a capacitor, XC = −1 ωC. X C = − 1 ω C.
The equivalent capacitor for a parallel connection has an effectively larger plate area and, thus, a larger capacitance, as illustrated in Figure 19.6.2 19.6. 2 (b).
