Connecting the N and PE lines together can provide a stable reference potential for the inverter, ensuring the stable operation of the system. This connection method can also prevent system voltage drift, especially when there are large load changes or inductive loads in the system, which helps maintain stable voltage output.
Another category of multi-level inverters is the so-called “fying capacitor” approach: Flying Capacitor + diode clamped converters are examples of “multilevel” Converters. This approach has become very common @ high power (and sometimes in low-voltage CMOS design!) Balancing of the intermediate voltage levels is always an issue.
ABSTRACT Nonisolated three-level inverter has the problem of leakage current and neutral-point (NP) potential imbalance in photovoltaic grid-connected system. Therefore, a new subregional vector-op...
In addition, when a fault occurs in the system (such as equipment leakage), the N-PE wires connected together can guide the fault current to the ground, trigger the action of the protection device, cut off the power supply, and thus protect personal and equipment safety. （2） Provide stable voltage reference
