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 IGBT. 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 (
communication control between main control part and elements using optical cable.
