Single-Phase Direct-to-Mains Connection Topology
Figure 8: Non-Isolated Single-Phase Connection Topology
The Power Supply is connected directly to the Mains AC line.
Warning:
Do not connect VN- to PE. In a direct-to-mains connection the VN- must not be
connected to the PE, as this will cause irreparable damage to the system.
Take care 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.
