4 MVW-01 WITH 5 LEVELS (5L)
The MVW01 5L line intends to meet the demand at lines with higher voltages and, thus, a specific topology and modulation are used.
It uses with the power section structure of H-type bridges connected in star, allowing the inverter operation in 5 levels.
Mains supply: 3~50/60 Hz
Input transformer
MVW01
Input cubicle
Main circuit breaker
or contactor
Diode input
rectifier
(36 pulse)
Output reactance
DC link
capacitors
Multilevel inverter
NPC 3 or 5 levels
Figure 4.1: Power section structure of the 6.9 kV line
Considering that 3 isolated DC links are necessary in this topology, new parameters for the voltage readings of these busses were added,
together with the new parameters for the temperature reading of the rectifiers, added to feed these new DC links.
