APPLICATION OF DSPACE FOR ANALYZING DIFFERENT CONVERTERS

Abstract

This report emphasizes on operation of dSPACE DS1104 R&D Controller Board, understanding some of the functions that it can perform and further analyzing these functions for some specific purpose. Here, the work has been done on this kit by successfully interfacing it with MATLAB Simulink. After completion of interfacing, some of its application using MATLAB Simulink like Digital Output, Digital Input, DAC Output, ADC Input and PWM waveforms would be studied. This report will also summarize how dSPACE DS1104 R&D Controller Board is better than other PWM signal sources. Once the PWM patterns are obtained, these would be used as an application to power electronics for designing and analyzing different converters like Choppers and Inverters. These convertors would operate in open loop as well as closed loop. dSPACE facilitates the user with real time simulation using which the user can vary the parameters while programs is running and observe the real time changes in parameters, this function of dSPACE will also be utilized. PWM output of dSPACE can be used to control the switching of the MOSFET used as switch in the circuits. Earlier TMS320F2812 DSP trainer kit was used for triggering switch. There were some cons in using it which was overcome by using dSPACE. This report will also present a comparative study of TMS320F2812 DSP trainer kit and dSPACE RS1104 controller board. These convertors will not only be designed and analyzed in MATLAB but would also iv

be realized physically on general purpose PCB and breadboards. Hardware implementation and its troubleshooting is generally a rigorous and tedious process. This work will include hardware implementation of different converters and the challenges faced while its implementation and troubleshooting. Best possible results of those hardware circuits would be obtained and will also be enclosed in this report.
