Abstract

In this paper a new Z-source frequency converter with silicon carbide (SiC) components is presented. Both, the motor side and the line side converter, contain SiC-VJFETs using the reverse-conducting capability for freewheeling. The application of SiC transistors with their low switching losses, allows high switching frequencies (up to 125 kHz), so the volume of the DC-link and filter components is reduced.
