| Abstract | ||||
| In this paper the dynamic performance of the wound rotor induction motor operating with synchronized modulator is considered and analyzed. The proposed modulator employs a PWM transistor-controlled capacitive network in rotor circuit with a carrier fiequency proportional to the rotor voltage frequency. This modulator can reduce the harmonic current components of the motor and consequently improve the motor power factor. The reduction of these components is achieved instantaneously with no need for sensing or computing the harmonics current in motor current, thus simplifying the control system. Simulated and experimental results obtained from closed loop O.5KVA prototype confirm the feasibility and features of the proposed system. | ||||
