Thyristor Electric Motor Drives (EB03) brings students in contact with the same industrialgrade components used in industrial electric motor drives. Students learn SCR control and PWM principles while acquiring skills including operating full-wave SCR DC motor drives, DIAC-controlled TRIAC AC motor drives and Schmitt Triggercontrolled TRIAC AC motor drives. The skills-based curriculum builds on the concepts learned in the prerequisite Industrial Power Electronics courses. Thyristor Electric Motor Drives (EB03) presents fifteen additional skills and eight additional Flexponent‚Ñ¢ panels.
