3.2 nverter features
N5000 is a Cascaded H-bridge type voltage inverter, which generates high 3-phase voltage by
cascading single-phase low-voltage inverters of insulated DC part. Multi-winding transformer is used
for numbers of independent insulated DC parts. And input harmonics content is reduced by installing 36
pulse (3kV class: 18 pulse) diode rectification part with phase differences of windings.
The improved structure enabled N5000 to generate high quality output voltage without a filter
that reduces harmonics and to utilize previously established motors and cables.
3.2.1 Composition
N5000 is composed of transformer panel, inverter (power cell unit) panel and control panel as
shown in Figure 3-1.
Figure 3-1 composition of N5000 inverter panel
A dry type multi-winding transformer is equipped in transformer panel. The 2
nd
winding of Multi-
winding transformer is constituted of 3 phase-6 winding groups with 10 degree phase differences
so that each winding is connected to the input terminal of power cell unit inside inverter panel for
6kV class. And the 2
nd
winding of multi-winding transformer for 3 kV class is constituted of 3
phase-3 winding groups with 20 degree phase differences.
Cooling fans are installed on top of all transformer panels for both 3kV and 6kV classes. The air
groove is separated from inverter/control panel and used for self cooling.
Each phase of U, V, and W has its own serially connected 6 power cells so that the total number
of power cells is 18 for 6kV class. For 3kV class, each phase of U, V and W has serially connected 3

power cells so that the total number of power cells is 9.
Every cell has the same electrical and structural shape and acts as a single phase inverter by
using GBT power semiconductor. Each cell has its own control unit. Power cell control unit and
main control unit are connected by optical cable. Air, which is inhaled from front panel filter, goes
through heat sink of power cell unit, air groove and then exhaled out of cooling fan on top of the
inverter.

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 nverter 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. nverter 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.”

Figure 3-4-B. 3kV-class N5000 inverter electric circuit
DC power supplies for the power cells of 18 H-bridge type should be separated to generate
6600V/6000V voltage output in 6kV-class N5000 series inverter. So the number of the 2nd
windings is made equal as the number of the power cells by utilizing multi-winding transformer. 6
windings (3 windings in 3kV-class) of each group have 10 degree phase differences (20 degree in
3kV-class) with each other by grouping the 2nd windings to 3 phases to minimize the harmonics
which are generated by using diode rectification circuit in each of the power cells. The transformer
of this type makes rectification part of 36-pulses for 6kV-class and 18-pulses for 3kV-class so that
the THD (Total Harmonic Distortion) ratio of the 1st side of transformer can be reduced below 5%
which is complied with the EEE std. 519-1992 (Harmonic Voltage and Current Limits).

3.3.2 Power cell circuit
All power cells within N5000 inverter are of the same structure and composed of the same
electric circuits. They are operated as a inverter of 3-phase 640V intput type. Each power cell
consists of parts of the power supply and the control. Power supply part is consisted of parts of
the diode recification and the single-phase inverterusing GBT. Capacitors are installed for the
protection of instant electrical failure and as the smooting-voltage circuit in DC part. Compulsive
air cooilng method is used to cool down the power elements using aluminum heat sink.
The Control part of power cell consists of the devices for power control and the DSP control
board. The devices for power control are supplied from main DC supply and make DC supplies for
controlling. DSP control board implements voltage PWM (Pulse width modulation) which generates
a voltage value determined by main control part, protective functions for DC over-voltage,
disconnection of input fuse for power cell and heat-sink and CAN ( Controller Area Network)
communication control between main control part and elements using optical cable.

640V from transformer is raised up to 850V in rectification part of power cell. And power cell is
modulated to generate 635V/577V for the inverter final 6600V/6000V output because 6 power cell
outputs are serially connected for each phase in 6kV-class inverter. (Each power cell output of
3kV-class has the same value with the 6kV-class because 3 power cells are serially connected for 1
phase in 3kV-class.) Power circuit connections for power cell unit use busplates and busbars to
minimize parasitic inductance effect. nverter circuit of the power cell inverts DC voltage to single
phase AC voltage and implements PWM for output voltage using on/off controllable GBT.
3.3.3 nverter Output
Maximum size of output voltage of each power cell unit is 635V. n the 6kV-class N5000 inverter,
six 635V units are serially connected to achieve 3810V and the 3810V units generate 6600 line
voltage using Y-connection as shown in figure 3-9.
※ nside value of ( ) is the voltage when considering maximum N5000 inverter output as 6000V.
