Content (Syllabus outline):

a) Review of High-frequency DC/DC converters and their detail analysis. Converters, with galvanic transformer, resonant converter

  • Switching losses, snubber circuits, triggering circuit for IGBT and MOSFETs
  • Requirements for steering and control of DC/DC converters, modulation principles, optimization of control loops
  • Design, criteria for selection of basic electronic components to operate in switching mode, the calculation of magnetic components, design of associated electronic circuits for measurement and processing of electrical quantities in power electronics circuits
  • Simulation of power electronics circuits.

b) Review of converters to drive DC, induction, BLDC Motor and their operation principles.

c) Uninterruptible power systems (UPS), plants (PFC) and measures (active and passive filtering) to minimize contamination of the network.

d) Electromagnetic compatibility, sources and methods of propagation of electromagnetic disturbances, actions and components to reduce the EM interference.

Objectives and competences:

Merging the power electronics sub-assemblies and subassemblies for industrial electronics in power devices and systems in terms of reliable and safe operation. Deepen insight into the design and operation of switching power supply systems from the selection of circuit elements to optimize the internal control loops. To prepare the students for in-depth analysis of power electronics devices and to independently design, realization and optimization of switching converter systems.
