3.3 Operation

N5000 inverter is a Cascaded H-bridge type voltage inverter, which generates 3-phase voltage
using serially connected single inverters (power cell unit).

3.3.1 Inverter circuit

Figure 3-4 shows the 6kV-class inverter power circuit. 3 phase power supply is supplied to each
of the power cell units through input transformer. Inverter of a power cell unit generates variable
voltage and variable frequency of single phase. And then the 6 power cell units are serially
connected to compose the output phase power. Finally, voltage between lines is generated through
Y connection between phases. Electric circuit of this type is named as "cascaded H-bridge
multilevel."
