EJ2311 Modulation of Power Electronic Converters 6.0 credits
Effektelektronisk modulation
Modulation of power converters plays a decisive role in modern power electronics where low losses as well as dynamical requirements, harmonics and electromagnetic interference (EMI) are of great importance. The course covers synthesis and analysis of modulation methods for Voltage Source Converters (VSC).
