Abstract The present paper shows the design and implementation of a SCADA system enabled to acquire signals from eight power electronics remote units plugged into a CAN bus. The power electronic modules are used for electric power conversion and electric machinery control systems. A 1KW full wave half-controlled rectifier was used as circuit under test to validate the signal acquisition and signal process to obtain the signal average, THD, RMS, and other characteristics. A digital oscilloscope FLUKE43B was used for comparison and validation purposes.
