摘要: A pulse width modulation (PWM) scheme for multilevel inverters is proposed. The proposed PWM generates the inverter leg switching times, from sampled reference phase voltage amplitudes and centres times middle vectors, in a sampling interval, as case of conventional space vector (SVPWM). SVPWM scheme, presented inverters, can also work overmodulation range, using only voltages. present technique does not involve any sector identification considerably reduces computation time when compared to technique. signal generation be used configuration. five-level configuration, an open-ended winding induction motor drive, verify experimentally.
