Three Level Diode Clamped Inverter for Field Oriented Control of Induction Motor

Indirect Field Oriented Control is a control technique used in AC drive systems to obtain high performance torque control. Sine pulse width Modulation is used for control the three level diode clamped inverter. In these applications, a rotational transducer such as a shaft encoder senses the speed of rotor. PI controller is then used to alter the firing pulse of three level diode clamped inverter regulate the output voltage to achieve the reputed stator current. The work of this project is to study and evaluate the FOC with open loop and close loop control of three level diode clamped inverter applied to the induction machines through simulations. The simulations were carried out using PSIM simulation package.
