DSP implementation of a naturally commutated matrix converter open loop control

By El Hadj Miliani, Daniel Depernet and J.M. Kauffmann

Abstract

International audienceThis paper deals with the design concept of a naturally commutated matrix converter control system. Matrix converters provide an all-silicon solution to the problem of converting AC power from one frequency to another, offering almost all the features required of an ideal static frequency changer. Until few years ago, control of switch mode power supply systems used analog controllers. Digital signal processors (DSP) are emerging as the processors of choice in monitoring and control of power electronics systems. In recent years, with the progress of high speed, lower cost digital signal processing (DSP) there has been a blossoming of the use of DSP techniques especially in power converters control. Using the 16-bit fixed point TMS320LF2407 DSP of Texas Instrument, a control strategy is implemented and tested on a 3 KW variable speed constant frequency generating system (VSCF) by using a naturally commutated matrix converter (NCMC)
