A Simplified and Fast DSP-CPLD-Based Implementation Method of Space Vector Modulation Applied in Indirect Matrix Converters

摘要

This paper proposes a new switching implementation scheme for an Indirect Matrix Converter (IMC) that can be suitably implemented using a low-cost 32-bit fixed-point DSP (TMS320F2812) operating at 150 MHz and a functional digital logic programmed in Altera (EPM7128s). The proposed method is based on carrier based PWM signals, has less computational complexity and can be implemented with very high speed and resolution. Simulation and experimental results obtained from a 5 kW converter are shown to support the given theoretical analyses and verify the full functionality of the proposed scheme.
