Inverter type IAC for air compressor drives

Highlights

Power supply by 3AC-/DC-board network or vehicle battery
V/f-control for compressor motor
Soft start function for compressor motor
Control and monitoring of the entire air supply unit
Communication with TCMS via binary inputs/outputs

Technical description

The IAC inverter is used as the central control unit of the air supply unit within a rail vehicle. The following functions are realized by the IAC:

Control of the compressor speed
Dryer control depending on compressor speed (changeover/regeneration logic and heating control)
Operation of the compressor on the DC vehicle battery
Motor temperature monitoring
Basic inverter diagnostics (e.g. voltage and current monitoring)
Control of an e-fan
monitoring of the air supply unit (e.g. air pressure)
(optional) Communication via CAN with TCMS

The IAC inverter is supplied from the 3AC/DC on-board power supply grid or the DC vehicle battery (optional).
