Many Faces of the Maximum Power Transfer Theorem

Abstract

The celebrated maximum power transfer theorem, which is usually stated for source impedance Z_g = R_g + jX_g and load impedance Z_L = R_L + jX_L, is revisited, and generalised for other possible situations in which either Zg or ZL or both are parallel combinations of a resistance and a reactance, and for all possible cases of load variability. Many of the results are believed to be new.
