Today's technicians are expected to maintain increasingly sophisticated Variable Frequency Drive systems with minimal downtime and limited free support.  These seminars bridge the gap between theory and practical fault isolation through hands-on fault analysis and component tear down and repair of actual VFDs systems.  Students will be probing and isolating real-world failure scenarios.  Participants will learn how to isolate faults and bench test output power IGBTs, DC Bus Rectifiers  &  gated Thyrestistors gaining valuable insight into how VFD components operate, and how they fail.   Our mission is to shorten the learning curve by sharing decades of field experience which make them safer and more comfortable through hands on fault finding experience.
