This paper starts by analyzing the modulation requirements of a single-phase H-bridge -source inverter, and subsequently extends the analysis to cover the more complex three-phase-leg and four-phase-leg -source inverters, with carrier-based implementation reference equations derived for all the inverters. The theoretical and modulation concepts presented have been verified both in simulation and experimentally.(This paper starts by analyzing the modulation requirements of a single-phase H-bridge-source inverter, and subsequently extends the analysis to cover the more complex three-phase-leg and four-phase-leg-source inverters, with carrier-based implementation reference equations derived for all the inverters.
