New concept of 2-phase electronic drive system for home-, industrial and transport applications
The paper deals with power electronic two-phase orthogonal system for home-, industrial- and transport drives applications with IM/PMSM motors. It consists of two-stage converter comprises: resonant LLC converter with AC output, twophase matrix converter commutated by HF AC input voltage, and two-phase induction/synchronous motors. The proposed system with AC interlink, in comparison with currently used conventional systems. As a consequence of that the advantage is then less number of semiconductor devices. Such a configuration features a good efficiency of electronic converters (due to soft switching of both converters) and also good torque-speed characteristics of two-phase AC motors.
