PERFORMANCE ENHANCEMENT OF THE INDUCTION MOTOR HYBRID DRIVES THROUGH COMMON MODE VOLTAGE COMPENSATOR

Abstract

Abstract— In the present years, the world is facing the global warming crisis rigorously in many countries. And it is slowly extended to one nation to the other nation. The existence of humanity is more complicated as the commercial trends are going to be like this. To limit this some of the countries are followed even/odd numbered formula, i.e. even and odd number vehicles are allowed day after a day. So therefore it is correct time to explore much about the electric vehicles. In particular, the research is based on the induction motor implementation in the electric vehicle because of extraordinary starting torque and good efficiency. The induction motors are carrying out through high-frequency pulse width modulated inverters, when applied in hybrid electric vehicles. Since the high-frequency switched inverters, it will build lots of troubles at input side of the motor. Out of all problems, common mode/differential mode voltages are some of the foremost problems. The common mode voltage is the mirror image of shaft voltage that will create voltage via motor air gap, resulting raises motor bearing current, therefore premature damage to motor steadiness and natural life. For compensating and testing the problem, some experimental model is developed. The objective of this representation is to assess the electromagnetic interference at the time of drive under test.
