Catalog Description

Analysis and design of AC-DC and DC-DC converters. Linear, basic switching, charge-pump, and fly-back topologies. Introduction to devices used in a powerswitching supplies. Thermal management. Integral laboratory.

Course Objectives

  • Analyze and design linear regulator topologies including Zener based, pass-transistor based, and pass-transistor/Op-Amp topologies.
  • Analyze and design switching regulator topologies including buck, boost, buck-boost, and flyback topologies.
  • Analyze and design charge-pump topologies.
  • Solve the convergence problems of using computer based simulation tools for the analysis of switching circuits.
  • Use standard components found in switching topologies including control integrated circuits, gate drivers, and current sensors.
  • Identify the differences between components used in switching circuits as compared to other circuits such as electrolytic and polyester capacitors, and low and high inductance resistors.
  • Identify component failure mechanisms such as how lifetime is related to peak and RMS current ratings.
  • Identify to how circuit layout affects circuit performance.
  • Design,construct, test, and operate 50 W linear AC-DC and switching DC-DC power supplies.
  • Use the fabrication tools and techniques necessary to prototype power supplies.
  • Analyze and properly manage the thermal aspects of power electronic circuits.
