Minimization of Switching Losses for Diode Clamped Multilevel Inverter
International Journal of Computer Applications, 2012 Multilevel inverters are emerging as a most promising alternative for reducing the harmonics and to achieve highvoltage, high-power capability but switching losses are increased because of increased device count. Many modulation techniques like soft switching techniques, space vector-based PWM techniques or sinusoidal PWM-based techniques were employed
