Riding the Reflected Wave to Improve Variable-Speed AC Motor Reliability
Overview The increased use of variable frequency AC drives with fast switching power semiconductor technology is creating new application issues regarding the installation of these drives. The most significant of these issues is the impact of these advanced semiconductors on the motors used in the installation. AC drives with IGBT (Insulated Gate Bipolar Transistors) power semiconductors located at a distance from the motor have the potential of producing reflected waves. These waves can cause high voltage spikes at the motor’s terminals, which can produce destructive conditions to the motor’s insulation and result in motor failure.
