| Abstract: | In this paper, SPWM control technology is applied to matrix converter. SPWM strategy of matrix converter is deduced. Control switch functions of matrix converter do not need complex mathematics deduction and calculation. The control system of matrix converter is designed by using TMS320F240 DSP. The control methods of the system are analyzed. The block diagram of hardware and the flow chart of software are given. The system not only meets the requirements of real-time control and demonstrates high performance, but also simplifies the software and hardware of the system. |
