Abstract :
The paper describes a possible solution for time-discrete load voltage measurement. Instantaneous value of the voltage is obtained using a microcomputer driven analogue adaptive filter. The proposed evaluating method is verified through simulation and experimental results. Beside results of voltage filtering, a potential use of the method in sensorless control of an induction machine and its limitations are also investigated.
