Description: 

he main component of modern Power Electronics circuits is the semiconductor power switch. This course presents the fundamentals of Power Switches operations from a physical point of view, together with the specific peculiarities and the reason to use them in a special application.

An overview on different packaging technologies and their properties, advantages and disadvantages, is also given. Requirements from the applications and possibilities to tackle them with a semiconductor package solution will be proposed.

Day 1

  1. Lecture : 08.30-12.00 (V. Popok, K. Pedersen)
    • Junction theory, PN- and PIN-diodes.
    • Fundamentals of bipolar junction and field-effect transistors.
    • MOSFET and IGBT in power electronics.
    • Emerging (wide band-gap) technologies.
  2. Lecture 2: 13.00-16.30 (F. Iannuzzo)
    • Operation of MOSFETs and IGBTs. On state, off state, switching theory. Miller plateau, voltage/current overshoots and voltage/current tails. Power loss calculation.
    • Overview of abnormal operations: Safe Operating Area (SOA), unclamped inductive switching (UIS) and short circuit.
    • Principle of instability theory: current crowding and thermal runaway. Negative capacitance.
    • Modern driving strategies: including two-level turn off and desaturation protection

Day 2

  1. Lecture 3: 08.30-12.00 (E. Hoene)
    • Introduction on packaging techniques for modern semiconductor power switches.
    • Challenges in terms of power density, stray inductance/resistance and reliability.
    • Modern interconnection solutions: copper bond wires, low-profile packaging, bondless packaging, etc. 
  2. Group work, part 1: 13.00-16.30

Day 3

  1. Group work, part 2: 08.30-12.00
  2. Final lecture: 13.00-16.30 (F. Iannuzzo, E. Hoene)
    Project presentations by groups, Collective project verification and discussion

Prerequisites:

basic knowledge of circuit theory

Form of evaluation: 

the participants will be grouped and asked to work in team on a real design. Groups will compare and deeply discuss the achievements and the design choices in the final 1-day lecture. Attendees are asked specific questions about the developed design to be answered individually.

Price

6000 DKK for PhD students outside of Denmark and 8000 DKK for the Industry.
