Abstract |
The objective of this project is to model and simulate a three-phase Voltage Source Pulse Width Modulation (PWM) Rectifier Based on Direct Current Control feeding an indirect vector controlled Induction Motor Drive (VCIM) . Based on the mathematical model of PWM rectifier, the dual close loop design with decoupled feed-forward control is applied to the three phase voltage source rectifier. The objective of this project is to model and simulate a three-phase Voltage Source Pulse Width Modulation (PWM) Rectifier The first objective is to realize unity power factor at the input ac mains and regulate output voltage. The second one is to realize that the above designed PWM rectifier will always give its objectives of stiff dc voltage and unity power factor irrespective of the load and its controlling methods. Considered resistive load on rectifier and check the performance of the PWM rectifier with direct current control. The induction motors is taken with indirect vector control and consider a load on inverter, so as to reflect the most practical aspect of the load for checking the viability of the rectifier design. The operation of Induction machine is not disturbed the PWM rectifier objectives. The designed PWM rectifier is considered as capable of feeding the Common DC coupling point(dc bus). |
