Fuel cell (FC) is considered as an attractive power source for the application of the distributed power generation system. A three-level power conversion system (PCS) for fuel cell is investigated. To suppress variation of the neutral point voltage of three-level inverter and prevent fuel cell from the low frequency current ripple under unbalanced load, a novel power management unit (PMU) and its...
Problem of neutral-point voltage unbalance is a key issue for 3-phase 4-wire 3-level NPC inverter. This paper analyzes the relationship between the neutral point voltage and the neutral point current. Neutral-point voltage problem is transformed into neutral-point current problem. Then value of neutral-point current under balanced and unbalanced load condition is calculated. According to the mathematical...
