| Abstract: | This paper gives thorough analysis on voltage oriented control algorithm of three-phase voltage source PWM rectifier in three-phase four-wire systems. Corresponding mathematical model, basic equations and control block diagram are introduced respectively. Voltage balancing control and pulse width modulation strategy are explained in detail. To verify the correctness and facility of the presented algorithm, a simulation model based on Matlab7.1 has been built. Simulation results show, this algorithm is reliable, easy to be implemented, and suitable for industrial applications. |
