ABSTRACT:
A pulse-width-modulated inverter in which equations relating switching angles, d.c. link distortion and a.c. inverter output distortion are determined empirically or by computer modeling. The amplitude of a d.c. link harmonic is the equation variable and stored constants particularize the equation for the phase of the harmonic and each switching angle which is to be controlled in response to d.c. distortion. As the d.c. link harmonics change, switching angle modifications are calculated using the stored constants.
