Motor Control: VFD

Catalog description

This course is restricted to students presently studying under the direction and oversight of an approved apprenticeship program, working in partnership with Columbus State Community College. This course continues to build on motor control skills by introducing (Variable Frequency Drives (VFD)as a viable option for the start/stop and RPM control of motors. Topics include: fundamentals of VFD, AC frequency versus motor RPM, motor slip, Fundamentals of PWM (Pulse Width Modulations), Diode Bridge/Filter/IGBT (Insulated Gate Bipolar Transistor) methods, IGBT versus SRC for output inverters, cost saving applications for VFD, BFD startup procedures, and interconnection of VFD with energy management systems.
