Technical FAQs 4

How to reduce voltage deviation at neutral point of NPC inverter?

The voltage deviation at the neutral-point of NPC inverter is reduced by appropriately selecting the redundant vectors to counter the effect of medium vectors. However, rearrangement of switching sequences requires huge efforts especially for multilevel inverters which possess high number of switching states.

How to determine if an inverter is able to reduce voltage imbalances?

The various aspects provided are power rating, switching frequency, DC-link voltage, control update time, and modulation scheme which are all very important in evaluating the inverter’s ability to reduce voltage imbalances.

How do differential inverters develop the PWM of internal DC-DC modules?

Abstract: Differential inverters develop the PWM of internal DC-DC modules by correlating fundamental frequency of load with high switching frequency to maintain inherent characteristic operation and achieve pure higher/lower AC output voltage with smaller size.

Should multilevel inverters be applied at low voltage side?

However, from another point of view, other than medium voltage applications, it will be interesting to apply multilevel inverters at low voltage side due to their unique capability in distributing voltage burden among power switches, thereby lowering the voltage stress in each power switch.
