The purpose of this thesis is to investigate and implement an optimal firing strategy for harmonic distortion minimization in variable frequency control of three-phase inverters. Optimal techniques for the minimization of harmonic distortion previously developed at Ohio University were adapted to calculate firing strategies for variable frequency applications. A control program was developed to execute the variable frequency control. A lab inverter was configured to demonstrate the minimization technique. Lab data was collected and compared with calculated values. In conclusion, harmonic distortion is effectively minimized for variable frequency control applications using the optimal technique.
