| Abstract | ||
| This paper introduces an analytical and experimental investigation for both dynamics and steady-state of a dc series motor fed from a single-phase AC to DC pulse width modulated (PWM) voltage source converter. The source impedance as well as the saturation effects were taken into consideration. The differential equations describing the system behavior in the different modes of operation are given. Solving these equations using fourth order Runge-Kutta method enabled the prediction of the motor performance in both transient and steady-state conditions. The large chopping frequency facilitate the input filter requirements of the supply current. The supply current, which is considered sinusoidal, can be controlled with a near unity power factor. The complete performance is verified expcrimentally where close agreement between the computed and test results is achieved. | ||
