25TermsLine-side converter: A converter that is connected to the supply network and iscapable of transferring energy from the network to the DC link.Motor-side converter: A converter that is connected to the motor and controls themotor operation.Operation principleThe line-side and motor-side converters consist of six insulated gate bipolartransistors (IGBT) with free wheeling diodes.The converters have their own control programs. The parameters of both programscan be viewed and changed using one control panel. The control panel can beswitched between the converters as described on page 86.Line-side converterThe IGBT supply module rectifies three phase AC current to direct current for theintermediate DC link of the drive. The intermediate DC link is further supplying themotor-side converter that runs the motor. The line filter suppresses the AC voltageand current harmonics.By default, the converter controls the DC link voltage to the peak value of the line-tolinevoltage. The DC voltage reference can be set also higher by a parameter. Thecontrol of the IGBT power semiconductors is based on the Direct Torque Control(DTC) method also used in the motor control of the drive. Two line currents and theDC link voltage are measured and used for the control.Motor-side converterThe motor control is based on the Direct Torque Control (DTC) method. Two phasecurrents and DC link voltage are measured and used for the control. The third phasecurrent is measured for earth fault protection.The ACS800-31/U31
