MVW01 WITH 3 LEVELS (3L)
The DC link is composed by high reliable dry plastic film capacitors with long useful live used for filtering. The capacitor bank is distributed
through the power arms and split into two parts by a series connection that creates a medium point dividing the DC link into two voltages, VP
and VN.
The medium point is necessary to implement the inverter. The inverter is built in a three-level topology (NPC - “neutral point clamped”) using 4
HV-IGBTs (3.3 kV, 4.5 kV or 6.5 kV) and 2 clamping diodes per phase.
The complete inverter is assembled inside metallic cabinets with IP21 protection degree (IP41, IP42 optional).
