Generator control

The generator power flows through the generator-side converter to the converter intermediate
DC circuit.

The generator control is based on the Direct torque control (DTC) method. Two phase
currents and intermediate DC circuit voltage are measured and used for the control. The
third phase current is measured for ground fault protection.
