I will simulate a grid connected current source inverter with voc

PLECS 5.0 simulation of a grid-connected Current Source Inverter (CSI) fed by a thyristor rectifier, with Voltage-Oriented Control (VOC).

WHAT'S INCLUDED

6-pulse thyristor rectifier with DC-link current control (firing-angle PI, 14 A)

DC-link inductor 100 mH (current-source link)

CSI with reverse-blocking switches, 6 kHz carrier

CL output filter (4.7 uF / 3 mH) connected to a 400 V, 50 Hz grid

CONTROL

SRF-PLL grid synchronization

dq grid-current PI control with feedforward and decoupling

Capacitor-voltage loop with active damping of the CL resonance

Modulation-index limiter and Min-Max zero-sequence injection

CSI switching logic that keeps the DC current path continuous
