DSP-Based Pulse Width Modulation Generator For Very Spare Matrix Converter

Abstract

This paper present a modulation scheme for the Spare Matrix Converter (SMC) topology. The proposed method uses the space vector modulation (SVPWM) technique to control the converter’s rectifier stage and inverter stage. This method achieved the maximum modulation ratio of 0.866 with sinusoidal input/output current waveforms.

In the other hand, a simple real-time implementation method avoiding additional CPLD or FPGA devices is introduced. This technique is verified through simulation results using PSIM software and experimental results a 32-bit floating-point DSP (TMS 320F28335)
