Analysis and Simulation of Power Stage Voltage Controller Model Using Feedback Compensator

Abstract

This paper presents the design of power stage voltage control model under digital feedback compensator. The power high performance electronic system has to maintain stable voltage supply even though rapid change in power consumption in the load terminals. Hence, the efficient transfer function parameters selection of digital control system in the power stage converter is the most important in practices. To provide effective suppression in the output voltage corresponding to fast load change, correct feedback circuit with powerful transfer function has been suggested in this work. Close to output tracking of reference sinusoidal voltage is achieved by proposed techniques with fast rejection to sudden load variation. Furthermore, the obtained control system is robust against to reservations in the input DC voltage. The model is tested and evaluated under different performance in both transient operation and steady state requirements.
