3.3.3.2.b Single-Phase Direct-to-Mains Connection Topology
Figure 4: 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. 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.
