Aims

Identify and characterize the various power semiconductors. Study of operation of various types of electronic power converters. Study of the effects on the electric power grid (and loads) of the functioning of power electronic converters. Active, reactive, deformant and apparent power in the electric power system subject to non-sinusoidal alternating currents.
