Direct time-domain-based approach for study of space-vector pulsewidth modulation

Direct time-domain-based approach, which is characterized by the simplicity and clarity, is proposed for the study and design of space-vector based methods of pulse-width modulation (PWM) for standard voltage source inverters for adjustable speed motor drives. This approach is based on the detailed consideration of switching state sequences of three-phase inverter (with the corresponding duty-cycles), which are integrated characteristics of space vector PWM schemes and versions. It also permits providing of synchronization of output voltage waveforms and improvement of computational effectiveness of control algorithms.
