Abstract
This invention relates to a VSCF system for aircraft power generation having a DC source, the DC source producing a DC signal. An inverter is coupled to the DC source and produces a constant frequency AC signal from the DC signal. It is known that, in converting the DC signal to the AC signal, the inverter distorts the DC signal, producing harmonic content therein. Accordingly, an inverter controller is provided which analytically determines distortion of the DC signal due to inverter action and alters PWM patterns fed to the inverter to precompensate for harmonic content in the DC signal.
