3.5.3.3.a Three-Phase Direct-to-Mains Connection Topology
Figure 6: Non-Isolated Three-Phase Connection Topology
Caution:
• Do not connect VN- to PE. In a direct-to-mains connection the VN- must
not be connected to the PE. Connecting the VN- to the PE will cause
irreparable damage to the system.
• Be careful and note that in a direct-to-mains connection the Neutral point
is not the most negative voltage level. It is the mid-point level of the
rectified DC bus.
