Speed control of ac series motor using ac chopper voltage control

This paper presents a proposed modeling and numerical simulation of the speed control ac series motor fed from pulse width modulated ac chopper voltage control. The advantage of this system is its high power factor and less total harmonic distortion factor of the motor current. The digital simulation of this system is described the system behavior in the transient and steady - state conditions. The system performance characteristics are predicted using the proposed simulation program. A laboratory set up has been built and experimentally tested to examine the proposed system. Simulation and experimental results are computed and shown to be in good agreement.
