CIRCUIT OPERATION
Main Circuit Configuration
The following circuit shows some typical configurations of the drives. Input AC is supplied through
an input controller to transformer T1. The transformer has multiple phase shifted secondaries connected to
full wave diode rectifier bridges. The output of the rectifiers is connected to three inverter power modules
that produce 3-phase AC power at the frequency and voltage required by the motor. For 6600V drives, a
combination of three 2400V modules and three 4160V modules are used in series to produce 6600V.
