A simple double mapping based SVPWM method for balancing dc-link capacitor voltages of five-level diode-clamped converters

DC capacitor voltage imbalances are one of the major technical concerns for higher level diode-clamped converters (DCC). In this paper, a simple double mapping based space vector pulse width modulation (SVPWM) algorithm is proposed for balancing dc-link capacitor voltages of five-level DCC utilizing the switching redundancies. By choosing the appropriate… (More)
