Rapid prototyping applications on three-phase PWM rectifier and shunt active power filter

In this paper, the design procedures of a unity power factor pulse width modulated (PWM) rectifier and shunt active power filter (APF) using MATLAB/Simulink blocksets and code generation tools for TMS320F2812 fixed-point digital signal processor (DSP) is presented. A systematic design approach is given to develop a rapid prototype system in a reliable procedure. The design procedure uses Simulink model of the rectifier and shunt APF systems, control circuitry, real-time DSP program code generation. The generated and self-developed codes on DSP are tested with Simulink models; therefore, any possible error in the controller implemented within software is eliminated before connecting the power converter to the supply. The code generation tools of Simulink provide an efficient way in the transition from the analysis stage to real system implementation. The effectiveness of this procedure for safely starting up the system is experimentally verified.
