Space Vector Pulse Width Modulation Applied to the Three-Level Voltage Inverter
نویسندگان
چکیده
⎯Advances in power electronics technology allowed the wide investigation of multilevel converters that provide high safety voltages with less harmonic components compared to the two-level structures. Employed for converter's gating signals generation, the space-vector pulse width modulation (SVPWM) strategy reduces the switching losses by limiting the switching to the two thirds of the pulse duty cycle. This study aims to explain, via simple and easy algebraic expressions, the application of the SVPWM on the three-level voltage inverter. The theoretical study was numerically simulated using Simulink under Matlab software. Index Terms⎯Three-level voltage inverter, space vector pulse width modulation, DC-link voltage, sampling time.
