Matrix frequency converters in electric drives with synchronous motors Tyshevych B. L., Orlov M. V. Annotation In this article are analysed features of a matrix-using frequency converter with an electric induction motor, comparing with a traditional bridge frequency converter. Investigated are benefits of a matrix-using frequency converter during the work with correction for determining the exact position of the rotor synchronous motor. Key words: electric drive; synchronous motor with permanent magnets; matrix frequency converter; rotor position correction. A synchronous motor is an electric machine, rotor speed of which is equal to the rotation frequency of the magnetic field. Low power (10 kW) engines are mainly made of a permanent magnet rotor (SMPM). Currently, this type of an engine is the most promising for the electric drive. They have several advantages: high energy performance (90 % efficiency); smaller weight and size; wide range of rotation frequency; high overload capacity for the moment; long li
