This course gives you a fundamental understanding of the basic components that form a SMPS design and the installation, operation and troubleshooting of variable speed drives. You will understand how the selection of components affects the different performance parameters and operation of the SMPS. Typical practical applications of VSDs in process control and materials handling, such as those for pumping, ventilation, conveyers, compressors and hoists are covered in detail. The course also covers the basic setup of parameters, control wiring and safety precautions in installing a VSD.The various drive features such as operating modes, braking types, automatic restart and many others will be discussed in detail.

The course also covers the four basic requirements for a VSD to function properly with emphasis on typical controller faults, their causes and how they can be repaired. Even though the focus of the course is on the direct application of this technology, you will gain a thorough understanding of the problems that can be introduced by SMPSs and VSDs such as ripple, harmonics, electrostatic discharge and EMC/EMI problems.

NB: The course description of all EIT "Certificate" courses has been changed to "Professional Certificate of Competency". Some course brochures are not yet updated. The actual certificate received by successful students will include the new title.


At the end of this workshop you will be able to:
