Course Description

Explores modern applications of semiconductor devices with a focus on power electronics. Utilizes insulated gate bipolar transistors (IGBTs) to study the operation of buck and boost choppers, battery chargers, and pulse width modulated (PWM) inverters. Examines the construction and theory of operation of thyristors and their use in rectifiers, inverters, and motor drives. Prerequisites: EET 221. Audit available.

Intended Outcomes

Upon successful completion of this course, students will be able to:

  1. Identify power electronic applications of semiconductor devices.
  2. Apply semiconductor principles to analyze the operation of DC to DC, AC to DC, and DC to AC converters.
  3. Apply semiconductor principles to analyze the use of IGBTs and thyristors in controlling DC and AC power.
  4. Build and troubleshoot circuits by interpreting schematic diagrams, using instrumentation tools and computer software to observe circuit characteristics.

Outcome Assessment Strategies

Course Activities and Design

The determination of teaching strategies used in the delivery of outcomes is generally left to the discretion of the instructor. Here are some strategies that you might consider when designing your course: lecture, small group/forum discussion, flipped classroom, dyads, oral presentation, role play, simulation scenarios, group projects, service learning projects, hands-on lab, peer review/workshops, cooperative learning (jigsaw, fishbowl), inquiry based instruction, differentiated instruction (learning centers), graphic organizers, etc.
