Abstract

A full digital control of a voltage source converter (VSC) rectifier is presented. The behavior of the AC and DC sides were modeled and used for the design of the AC current tracking controller and DC voltage regulator. The AC current control, based on the deadbeat strategy is presented in a simple and intuitive way. The DC side PI controller is designed based on the linearized model of the converter. A simple and efficient Phase Locked Loop (PLL) based on the deadbeat strategy is presented. The performance of the complete system is verified by numerical simulation and experimental results, validating the proposed model and control strategy. Effect of parameter mismatch is also discussed.
