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.Results of simulation compared to experimental verification carried-out ones are given in the paper.
NEW CONCEPT OF A TWO-PHASE POWER CONVERTER IN ELECTRIC DRIVES FOR INDUSTRIAL AND TRANSPORT APPLICATIONS
The article concerns the application of a two-phase power converter in drives with an induction motor or a permanent magnet synchronous motor (IM/PMSM) for home, industrial, and transport devices. This system consists of: a resonant LLC converter with an AC output, a two-phase matrix converter commutated by a high-frequency AC input voltage, and a two-phase induction/synchronous motor.
The proposed system is characterized by a smaller number of semiconductor devices, higher efficiency of power converters, and good mechanical characteristics of two-phase AC motors compared to conventional systems. The results of the simulation and their verification based on laboratory results will be presented in this article. (…)
