Abstract :
The modeling and control of a PWM rectifier in the case of network variations are studied. The aim is to limit and stabilize stable variation of DC output voltage and line currents in such circumstances. A line current compensation loop method coupled with identification of network parameters is compared to another approach using a robust DC voltage regulator
