Hello. Please looks at the attached image first. The left image is LCC impedance matching network (one of T-type impedance matching networks) and the right is the corresponding equivalent circuit when CT and CL are adjusted such that an equivalent impedance of the sub-circuit surrounded by dashed-line becomes RS. You don't need to take care of what ZL really is, that was not important for my question I would like to ask you here. In the left circuit, there is only one resistance, RL, located in ZL so that's the only point that a real power (active power) is consumed. But in the right, Zeq itself is a purely resistive. In order to make sense in terms of power consumption, a real power at Zeq, I2Zeq = I2RS is same to I12RL, I think. But..RL can be a lower than RS and I1 is lower than I. As a result, two consumed powers are not equal. How can I solve this apparent contradiction? I think reactive powers for reactive components have some role to match these two power. For example, reactive components receive power over a quarter cycle and release it to the RL for another quarter cycle, not to the source. But I don't know how such an energy flow occurs. Could you please help to clarify this?
