Course detail

Laboratory of Electric Drives

FEKT-LLEPAcad. year: 2013/2014

The learning course continues with deepening knowledge gained in courses BEPB and MERP and creates then integrated educational block. Laboratory lessons are based on functional samples to verify theoretical knowledge. The computers are used for modeling and programing of real applications. The important part of the course MLEP are excursions to real manufacturing firms which are focused on electrical drives and power electronic
