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).
Highlights
The Matrix Converters are ac-ac power conversion devices that can provide flexible and controllable increment/decrement of both voltage and frequency amplitude. They have experienced a resurgence of attention recently [1]-[5] because of its advantages of adjustable power factor, bidirectional power flow, high quality input/output current waveform, and the possibility of a compact design due to the lack of large energy storage components
This paper focuses on analyzing the Spare Matrix Converter (SMC) topology because it has several advantages such as easy implementation, more secure commutation technique, the possibility of further reducing the number of power switches and the possibility of modifying
EXPERIMENTAL RESULTS In order to validate the effectiveness of the implementation method, an Indirect Matrix Converter prototype was setup experimentally
Summary
The Matrix Converters are ac-ac power conversion devices that can provide flexible and controllable increment/decrement of both voltage and frequency amplitude They have experienced a resurgence of attention recently [1]-[5] because of its advantages of adjustable power factor, bidirectional power flow, high quality input/output current waveform, and the possibility of a compact design due to the lack of large energy storage components. The main circuit of the IMC has two stages: rectifier has six bidirectional switches and inverter has six directional switches, as show in Figure 2 (b) [14] Both of two converters are able to generate input/output waveforms with the same performance and the same voltage transfer ratio capability. The use of a DSP combine with a FPGA module has been applied in many power electronics.
