| Abstract | ||||
| In this paper, a complete modelling and numerical simulation are given for a system consisting of a separately-excited dc motor fed from an AC to DC symetrical angle controlled converter through a Bridge rectifier and a power MOSFET. This work prcsents a detailed theoretical analysis and experimental results to improve the power factor via this converter. The differential equations describing the system behaviour in the different modes of aperation are given. Both transient and steady-state conditions are obtained by solving these equations numerically. Moreover, the effect of control voltage of the converter on the system performance is investigated. The computed performance is verified experimentally where close agreement .between the computed and test results is achieved. The results show that the present modelling and numerical simulation is accurate and convenient to obtin the speed controller parameters for closed loop speed control in order to provide specific response | ||||
