A Generalized Harmonic Injection Analysis Aimed at Improving Power Transfer

Harmonic Injection is a technique often used in Electric Power Systems for harmonic compensation control in distributed power plants and for optimizing power transfer and modulation distortion in switched-mode devices, among other applications. This brief presents a thorough mathematical investigation of the harmonic injection technique, generalizing the well-known third-order harmonic injection analysis to the problem of n-th order harmonic injection, and answering two open questions in the current literature: why is the third harmonic the only one used, and why are the even-order harmonics never contemplated?
