METHODOLOGY OF STUDY OF SENSORS SPECIFIC TO CONTEMPORARY ELECTRIC VEHICLES

Vasil Dimitrov

Contemporary electric vehicles are designed on the base of highly efficient asynchronous drives and microprocessor safety and control systems. Vector Control provides a stable speed irrespective of the load, low level of torque fluctuations, optimal values of energy indicators (power factor, efficiency, and harmonic distortion). The appropriate information support is necessary for the implementation of vector control: bits of information about the actual values of drive parameters must be given to control system in real time. The most important drive parameters are current, voltage and speed of the motor. In this paper, sensors which are specific to such applications are described: current transducer, instrumentation amplifier, rotary encoder. Methodology and algorithm of sensors tests are developed. Their goal is to determine the optimal value of the conversion factor.
