This project presents a three-level diode-clamped inverter feeding an asynchronous motor drive with direct torque control (DTC). The control method is based on DTC operating principles. The stator voltage vector reference is computed from the stator flux and torque errors imposed by the flux and torque controllers. This voltage reference is then generated using a diode-clamped inverter, where e...

On-chip parasitic inductance has become an important design issue in high speed integrated circuits. On-chip inductance may degrade on-chip signal quality, affect transmission delay, and cause additional short-circuit power dissipation.
