Study on programmable adjustable inductor application simulation in PWM Rectifier

In the control of voltage source PWM rectifier, direct current control and dual close loop control structure in d-q synchronous reference frame are widely adopted. Its simulation model is built up based on PSCAD software. AC side inductor has important effect on dynamic and static response of current loop. Inductor coil can be substituted for Programmable adjustable inductor. Simulation results show that not only enhancing transient response of current crossing zero, but also inhibiting harmonic peak current after adopting new component. The method possesses some practical values at the aspect of improving power quality.
