Single-Phase Direct-to-Mains Connection Topology
Figure 10: 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.
