Abstract :
A new PWM technique, capable of achieving a correct dc-link capacitor voltages balance in Diode-Clamped Multilevel inverters with Active Front End (AFE), beyond the limits defined by the theory for converters without AFE, is presented. A detailed explanation of the new devised PWM technique and the main results are reported with analytical computations.
