Power Electronics

Basics of electrical engineering and electronics

• Introduction
• Components of power electronics (passive, active)
• Analysis methods of power electronics (steady state, current and voltage ripple)
• Design of a DC/DC converter (design of L, C, semiconductor)
• Topologies of power electronics: DC/DC
• Topologies of power electronics: AC/DC, DC/AC
• Topologies of power electronics: Isolated DC/DC converters
• Analysis methods of power electronics (dynamic)
• Resonant converters and soft-switching techniques
• AC circuit power (linear vs. non-linear load, AC/DC, power factor, THD)
• Control of a power electronic circuit (gate driver, sensing, closed-loop control)

Students will be able

• to describe, analyze, dimension and construct basic power electronics circuits.
• to describe and apply selected components of power electronics.
• to explain and use specific properties of power electronic components and semiconductors.
• to analyze and switched mode PWM converter circuits.
• to perform efficiency calculations and simulations.
• to plot common topologies of power electronic circuits and explain their working principles.
• to explain the principle of operation of resonant converters.
• to use a control IC for a closed loop operation of a DCDC converter.
• to describe and calculate the power in an AC network.
