A modern power electron power component IGBT ( Insulate-Gate Bipolar Transistor) is used as the main power switch component of power converter. In the whole system, Intel 16 digits single chip microcomputer 80C196KC and EPM7128 EPLD (Erasable Programmable Logic Device) made in Altera Company are used as the controlling center.
It proposes an impedance-source (or impedance-fed) power converter (abbreviated as Z-source converter) and its control method for implementing dc-to-ac, ac-to-dc, ac-to-ac, and dc-to-dc power conversion.
The applications of MC (Matrix Power Converter) in DTC (Direct Torque Control) of induction machines are presented. With its good performances, the DTC technique attracts a lot of researchers to study on it, and get great improvements in recent years.
