| Abstract |
In this paper PWM methods for neutral point diode clamped three-level inverters are analyzed focusing on
power devices and DC-bus voltage utilization. For each PWM scheme considered, the conduction and
switching losses are computed for all devices as a function of the modulation indexes and of the load
power factor. Several modulation strategies are characterized in terms of DC-bus voltage utilization, total
harmonic distortion of the output voltage and losses in the power devices. Simulation results are included
to illustrate the impact of the PWM strategies in the inverter design. |
