This diagram shows the control interfaces and the main circuit of the drive.
 Operation
This table describes the operation of the main circuit in short.
Component Description
Six-pulse rectifier Converts the three-phase AC voltage to DC voltage.
Capacitor bank Energy storage which stabilizes the intermediate circuit DC voltage.
IGBT inverter Converts the DC voltage to AC voltage and vice versa. The motor operation
is controlled by switching the IGBTs.
