ECE 5204 Power Semiconductor Devices (3C)
Characteristics, fabrication, and application of power semiconductor devices, which may include p-i-n and Schottky diodes, insulated gate bipolar transistors, field effect transistors, and thyristors. Effect of semiconductor material, device structure, and current injection levels on device performance. Device drive requirements and power circuit interaction. Implementation of power devices using wide band gap semiconductors such as silicon carbide and gallium nitride.
Power semiconductor devices are the heart of power electronic circuits. Engineers working in the area of power electronic circuit design need to have a basic understanding of device capabilities and limitations and of the critical device-circuit interactions. Changes in the syllabus are a result of the significant advancements in semiconductor materials and device structures since the last course revision.
Typically offered: Spring. Program Area: Electronics.
Students will apply their knowledge of semiconductor materials, gained from the graduate course on semiconductor material and carrier transport, ECE 5200, to identify the properties needed for use in high electric fields and high currents and to understand why certain materials are used when fabricating power semiconductor devices.
