4.7.2.1.b Single-Phase Direct-to-Mains Connection Topology
Figure 11: 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.
