Abstract :
In this paper, a low cost and high performance current and voltage measurement system designed for application in medium voltage inverters is proposed. The main features of the proposed system are the use of commercially available integrated circuits and signal transmission from sensing point to the control board through an optic fiber link. Three single-bit oversampling analog to digital conversion systems are considered in this study. Simulation and experimental results are presented to confirm the high performance of the proposed measurement system.
