Radio Frequency (RF) Impedance Matching: Calculations and …
Therefore, the parallel combination of the 6.94 pF capacitor and the 1 kΩ load looks like a series 50 Ω resistor and a series capacitor with a reactance of –j218 Ω. Choosing a series inductor to give a +j218 Ω ensures the reactive parts of the matching network cancel and the 50 Ω source now feeds an effective load resistance of 50 Ω.

Capacitor Bank calculator or kVAR Calculation Formula
Note: if you want to calculate the capacitor bank in VAR/MVAR means, just enter the real power in W or MW. Example, if you are entering it in kW mean, you get kVAR only. The same way work for W and MW. Capacitor Bank calculation Required reactive power Q (kVR) is equal to the real power P (kW) times of the difference between tangent of cosine …
