This paper introduces a single-phase matrix converter (SPMC) excited rotary transformer system to replace the slip rings of traditional wound field synchronous machine (WFSM). Compared to an inverter excited rotary transformer system, the matrix converter is compact due to the absence of a bulky DC Link capacitor. In this paper, the proposed SPMC uses a new constant volts per Hz modulation method...
A novel over modulation methodology for dual bridge matrix converter (MC) is first put forward in this paper. Based on amplitude control of the rectifier side and inverter side, an over modulation methodology is presented. First the rectifier side is separated into six intervals to get the maximum DC voltage, and then a novel over modulation strategy is invented for the inverter side, which can manage...
In this paper the well-known voltage and current DC-link converter systems, used to implement an AC/AC converter, are initially presented. Using this knowledge and their space vector modulation methods we show their connection to the family of indirect matrix converters and then finally the connection to direct matrix converters. A brief discussion of extended matrix converter circuits is given and...
