Operation principle and hardware

Contents of this chapter
This chapter describes how the IGBT supply unit works and the hardware of the
ACS880-204LC IGBT supply module.
Operation principle
IGBT supply unit rectifies three-phase AC current to direct current for the intermediate DC
link of the drive. The intermediate DC link supplies the inverters that run the motors. There
can be one inverter unit only (single drives) or several inverter units (multidrives) connected
to the intermediate circuit.
The LCL filter is an essential part of the IGBT supply unit. The supply module does not work
without the filter. It suppresses the AC voltage distortion and current harmonics. The high
AC inductance smooths the line voltage waveform distorted by the high-frequency switching
of the converter. Capacitive component of the filter effectively filters the high-frequency (over
1 kHz) harmonics.
