If the reactance (X) of the load impedance ZL is positive, then we can use a series capacitor to cancel out this reactance, making the input impedance purely real. As an example, let zL = 0.3 + i when f =500 MHz. Then we can cancel out the reactance with a series capacitor, determined by:
Optimal Capacitor placement is an optimization problem which has an objective to define the sizes and locations of capacitors to be installed.
Series Capacitor and load impedance ZL. Mathematically, the series impedances will add. That is: From equation , we see that the series capacitor will move the impedance zL along the constant resistance circles of the Smith Charts, but in the opposite direction that the inductor moves it.
Now we will combine the two components together in series form and investigate the effects. Series capacitor circuit: voltage lags current by 0° to 90°. The resistor will offer 5 Ω of resistance to AC current regardless of frequency, while the capacitor will offer 26.5258 Ω of reactance to AC current at 60 Hz.
With series connected resistors, the sum of all the voltage drops across the series circuit will be equal to the applied voltage VS ( Kirchhoff’s Voltage Law ) and this is also true about capacitors in series. With series connected capacitors, the capacitive reactance of the capacitor acts as an impedance due to the frequency of the supply.
Two kinds of connections, and thus two kinds of applications, can be distinguished. One is where the capacitor is directly connected in parallel with the mains without any other impedance or circuit protection, and another where the capacitor is connected to the mains in series with other circuitry.
